Well the other day I fullfilled a long hope of mine.  I got a IBM Model M keyboard in the post.  I’ve been searching on and off for a nice keyboard and generally failing to find one that I like.  My most recent Apple keyboard is pretty crap and doesn’t really feel nice.  This board is a step in the right direction, but probably a step too far.

IBM keyboard use a two-stage mechanical keyswitch.  A buckling spring switch.  This is a totally mechanical switch, unlike the low quality membrane switches used in most cheapo keyboards.  If you can take the very strong feedback you get with a Model M, they are great.  Well built, reasonably priced, one can be had off ebay quite cheaply.  Or a store like clickykeyboards has a good range in stock.  They will last an awfully long time and are quite repairable.
