Current presses I would suggest the RCBS Rockchucker. I think it's the best single-stage press dollar-for-dollar.
If you can find an old Lyman OrangeCrusher press, those are great, it's what I have used since I got into reloading. The new Lyman press has a larger opening, allowing it to handle bigger cartidges like the RUM's easier, but there is a lot of play in the ram, and I'm not impressed by that. I wouldn't recommend them.
I have never tried Dillon, Redding, Forstner, Hornady or Lee presses.
