all the t-shirt and panini presses are a waste of time you'd have better luck with a hair straightener/clamp than most of them. I've done some looking around for a small personal set up and will likely get the 10 ton from canadian tire and some 3x3/4x4/3x5 plates. i was thinking from one of two people selling them on Instagram from canada, but the low temp plates look good too. For slightly bigger operations a 20-30 ton and some 3x6/4x7 plates is the way to go, imo.
the two people i was thinking of getting plates from.
