It's very expensive for a home grower. Last I checked, a heated hydraulic press was just not something I could purchase as a small home grower to justify its use at the price. Certainly if you plan on doing a lot of it, makes sense.
As a cheaper alternative, hot curling irons or whatever women call them at 2nd hand stores, especially if they have digital heat pads that can set temperatures, you can squeeze out a nug at a time.
