I've been lurking here for a while, deciding on a new keyboard for myself. I own 2 IBM Model Ms (one 1391401 that's about 10 months newer than me, and an 82G2383 from about '94). They're great, but big, and the lack of PS/2 ports on modern computers can make them cumbersome to use.
I ended up buying a Unicomp Spacesaver, and so far it's been great. It sits nicely on my laptop so I can use it instead of the laptop's keyboard (which I've had to replace 3 times since I got my computer). The sales experience with Unicomp was great, they shipped tuesday afternoon, and the keyboard was in Pittsburgh by Thursday (but I didn't get it until Friday because UPS was (justifiably) afraid of the snow).
Pics to come soon, I'm an amateur photographer working on a degree in computer engineering, so I'm sorely tempted to send some of the pictures to Unicomp to replace the blurry product shot on their website.
