I have used my Lyman 450 to size without having the lube reservoir pressurized and it works quite well. I am currently PCing all of my boolits and starting to collect different push through sizers. Yes, the Lyman works but so does a Lee hand press for sizing while watching football.
I've been using HF flat black for everything because I like the look and love the price. Some places sell by the pound for $16 bucks, HF is $5.50 for a pound. They sell red, yellow, white, and of course black. I've seen some pics of grey made by a guy who mixed the powders.
I use the HF PC gun but will be trying Rangefinders tumble method. The PC gun sells for $59, is occasionally on sale for $49, and if you have a coupon (like I used) you can get it for $39. As far as PC goes, I've tried it in .380, 9mm, .38/.357, 40, 41, 45 ACP and Colt, .223/5.56, 30 carbine, 30-06, and shortly 300 blk. Love it! I intend to try the tumble method for handgun but will stick with PC gun for rifle. My PC trays use gas checks to hold the boolits upright and keep PC from coating the check shank. Anyway, I'm digging the smooth shiny bores, the lack of smoke, and the lack of boolit deformation from semi auto feeding, especially the .223/5.56. Oh ya, the same powder charge with lead boolits obtain more velocity when PCd.
