So how much do these go for usually and how good are they? Im pretty used to typing on model M & F's
Not sure about the 104u, but my 87u was right around $200. That being said, they have stopped making the revision I got, and have since started making a rev2 (I think, if someone knows more please correct me).
As for their quality, I absolutely love mine. The steel plate really stiffens the whole thing up, and is the closest you're going to get to a Model M in terms of plate. The switches are obviously going to be a different feel: a lot less mechanical and instead more pillowy.
I would suggest trying out a 55g topre before buying if you can. I jumped in blind and relied on the praise from other GH members, and was lucky enough to quite like the feel. Others have no had the same experience thought.
