If it looks like a piece that sits flush with the back of the fork and takes an allen/hex wrench, it is recessed. See http://sheldonbrown.com/calipers.html for the complete run-down. Make sure whatever you get is the same (most newer calipers are recessed although tektro can usually be ordered nutted). The other main thing is that the reach of the calipers fits. You can google "measure caliper reach" to figure out how to do that. My guess is that any short or medium reach caliper will work, but it is worth checking. As an aside, my experience is that brake calipers usually aren't worth upgrading unless yours are broken for some reason or, maybe, you want to go from single to dual pivot (and this is a contentious thing to say for some). If your brakes aren't working well, odds are replacing the brake pads (especially if yours are original) will markedly improve performance more than just getting new brakes (other than those having new pads). People here (and I agree) seem to like the salmon kool stop pads; they're better than OEM. You could take your bike to an LBS and tell them you want some kool stop pads and they should be able to point out the ones that fit...and they aren't hard to replace and would be cheaper than new calipers.
