Making hash soon, will these pollen presses work?

I want to get a pollen press so I can get some good chunks of hash. Looking on ebay I found several ones, not sure what to get. Can anyone recommend anything? I found it very strange that some of the presses are $75+, and some are $10-$20, but they all look exactly the same to me. Is one overpriced or is it actually better? Any input appreciated! By the way, I will be making dry ice hash, already ordered bubble bags.

Here are some cheap ones: http://www.ebay.com/itm/POLLEN-PRESS-ALUM-5-PIECE-2-5-KIEF-3-COLORS-/110729630317?_trksid=p5197.m7&_trkparms=algo=LVI&itu=UCI&otn=5&po=LVI&ps=63&clkid=3521157011305311997

pressing hash is old school and bad form. check out my hash thread. https://www.rollitup.org/organics/367111-bubble-hash-aka-ice-wax-28.html#post6468945
