I’m considering buying a hardness tester. What are the best ones to consider, keeping cost in mind? Lee?
Thanks for all advice and opinions.

My Cabin Tree kicks ***. It is not cheap but it's very easy to use and if you don't use the hammer on it you'll have it forever.

I don't have any others to compare for accuracy, although to me my Lee seems to do the job well. Any test I've ever seen showed the Lee to be as accurate as any other hardness tester. It takes a bit of hand-eye coordination to use the microscope, but I have no problems even with my paws for hands. I would definitely recommend it.
I use pencils. Close enough for me.

This will help with pencil hardness testing

Cabin Tree tester is no longer made by same person but maybe available at http://www.cowboybullets.com/

I got a Lee and it works good for me for what I need.

You can miss fast & you can miss a lot, but only hits count.
I've got the LBT, which has a direct readout. I have my Dad's older Saeco as well. The LBT was pretty expensive, so I guess that doesn't help with the cost part.
The art pencils will probably be the cheapest and seem to work well. The Cabine Tree is easy to use and you can test ingots or larger chunks of lead with it. I've never used the Lee or the Saeco. Knowing the hardness is nice but it really does not tell you the alloy. It will help you guess at it.
Art pencils work and are cheap, Hobby Lobby, any craft store or art supply store has pencil sets numbered. They work well.
I have an LBT and a SAECO. Both work well for the purpose. The LBT needs flat surfaces, so I mostly use it for ingots. Sawing and filing the points off boolits so I can use it is too much work. The SAECO is the one I use the most, testing culled boolits from a casting session. I check point and base, and they are usually close, unless there is an air bubble in the sprue cutoff. I angle the base a little and retest when this happens.
I don’t see differences in accuracy between individual BHN numbers, just the ranges. If there is an optimum with the same boolit at BHN 8 vs. BHN 9, I can’t see it on the target. The difference between BHN 4-5, BHN 8-11, and BHN 14 and above is significant, in certain cases.
When I shoot black powder cartridge, or if I was to try for accuracy above 2000 ft/sec, a hardness tester is a help. For most of my shooting, using smokeless with Lino/wheelweight alloys or range scrap, hardness testing is too much information.
I use a Lee tester. I couldn't get the hang of their microscope, so use a magnifying visor. I'll use the "punching" unit and measure the indent with dial calipers. I can get really close to the 'scope measurements, and it's no great loss if I'm one or even two BHN numbers off from a laboratory test. My BHN readings are just for my own use and don't need to be within one BHN of what a foundry would find (and I cast fro mebbe 19 years before I got a tester)...

So what do these experiment prove? The differences between the various testers, the simplicity of using the tester making consistent readings possible, the users ability to use the tester consistently and interpret the results. This test also has shown how close to the lab tested sample (most of) the various testers really are.

I also when with a Lee, the results in the LASC test made it pretty apparent that if you are careful how you do it the Lee is the cheapest and most simple and accurate way to measure hardness. I had a Saeco that I inherited and I couldn’t stand it, I could test 3 boolits from the same batch and the BHN would vary and it wasn’t the easiest thing to read. The Lee is simple and gives relative results.

I started with pencils and got the Lee HBN tester. The pencils were consistent and accurate just like the Lee die. Just follow the directions with the Lee and it will be a repeatable and consistent. The Lee will match the pencils but i still considerate more of a reference and not so much an actual representation. I can accurately mix my alloys and create targeted BHN's for specific purposes with out actually knowing the content of my lead.

I owned a Seaco and a lbt. sold them both when I got my cabin tree. Hands down the best and cheaper then most.
