I have a 10 ton press and don't press over 4 ton. I haven't seen that adding any more pressure produces more yield. I also try to remember that temp. changes under pressure. 100 degrees under 4 ton of pressure is different from 100 degrees at barometric or atmospheric pressure. Although I think 20 ton is way overkill, 1 ton might also be under powering your setup. If my math is right, that's only 300 psi on a 3x5 plate.I purchased one of these, good price I feel overall, could probably build one for 1/2 or less the cost just like it but I feel its more than a fair price for ready to go out of the box.

I wonder where the line is of diminishing returns when it comes to pressure. This is a 1 ton, how much more product can you squeeze out with a 12 ton over a 1 ton I wonder. Could probably without to much trouble buy a harbor freight 20 ton and use these 5 x 3 plates and pid temperature controller on it if I wanted in the future.
Hey, I just looked at that press and it seems like a good deal. You'd pay close to that for the plates alone. No doubt you could also have someone create an adapter for it, if you ever wanted to move the plates to another press (with a round ram). This shop in Arizona makes some nice looking presses and plates. A 6/8 ton unit with 6" round plates can be configured for $520. http://www.mstract.com/rosin-presses/manual/mstract-manual-press-kit/I purchased one of these, good price I feel overall, could probably build one for 1/2 or less the cost just like it but I feel its more than a fair price for ready to go out of the box.
