What are /r/rosinpress' favorite Products & Services?

From 3.5 billion Reddit comments

Hey u/simmiauto I know this thread is 2 months old, but the only C words I say are "cock" and "cunt." Would you mind lending me your wisdom?

I'm tired of the yields from my girlfriend's hair straightener, and am looking to move up in the rosin world. Do you have a preferred model of frame from HFT that I should use?

If my math is correct, the final PSI would be the (Total Pressure/Surface Area) correct? So if I mounted these plates to a 10-ton frame, I'd have 20,000lbs/15in = 1,333PSI? Is there a recommended PSI for pressing flower? Additionally, I'm assuming 1g/inch is a decent packing density. I wouldn't anticipate pressing more than 7-14g of flower/kief at a time. Would a 10-ton frame be overkill, or do I need exceptionally high pressure in addition to heat?
