im looking into heat presses. i have one i got for christmas but its old and it has 2 temp settings. hot and OUCH WTF!! so my question is, if you have a clamshell press, what the thickest this you can sublimate on? mousepad, sublislate, etc. i know with a swing away you can do alot of different sizes. i can get my hand on a geo knight or a stahls press for less than 500 n they are both clamshell.
