I have an floor model etching press made in the 60's that weighs in at about 200 kilos and another that is portable, like this one. Either one will turn out a nice print, but the larger is more comfortable to use. Even more comfortable and predictable are the presses similar to the one you mention. There are lots of choices out there. Try to get access to a press at a local college or school and then make decisions as to what you want or need. To draw a photographic parallel, don't buy the ultra-large format Gandolfi before you've tried a 4x5. You might want it, you might not.
