I agree that the old IBM clickie keyboards were the cat's meow. Northgate (defunct, but remade?) made a decent clickie keyboard and I picked up a couple 2nd hand and have used them for years, although typing certain key combinations fast could cause problems (such as "HDS"!).
I recently found the Ione Scorpius-M10 mechanical keyboard and while it isn't as good as the old ones, it's one of the few, and rather affordable mechanical keyboards out now at $53. It's not too shabby, and it's what I'm typing on now.

Oh, and it doesn't have blank keys. How stupid is that?!?
p.s. What was even cooler was those IBM Selectric ('golf ball') electric typewriters. Talk about tactile (and audible) feedback! :-)
