I just bought a brand new Star sizer last month and they had them in stock, however I did have to wait a week to get my bullet feeder. It is a great piece of equipment and well worth the money. If you're not getting the bullet feeder I would strongly recommend adding a spring to keep the handle in the up position, if you don't do this you eventually sooner than later we'll get your finger pinched! I would also recommend setting up the machine with some kind of heat source to soften the lube, regardless what you use, It just plain makes things easier.
I also have rheumatoid arthritis and my main reason for getting the Star was that it can be automated with the air lube assist and a cylinder to actuate the up and down motion. This is a real benefit if you have RA. Before I got my Star I could only lube a couple hundred bullets in an evening, on my Lyman 450, without making my hands sore. With the Star, set up with lube air and stroke cylinder I can lube as many bullets as I wish and doesn't bother me a bit! If you are handy, and don't mind doing a bit of scrounging, you can come up with a parts to do a power assist on the handle for less than $100 (e-bay is your friend). Best money I have spent in a long time!
