Hmm, what are some other features?
e.g. weight; do you like a very heavy metal keyboard (3+ kilos)? In terms of angle, do you like an inbuilt positive (closer end lower) or negative (closer end higher) tilt? What sort of layout do you like; if you like 60% or in between it and TKL, what sort fits your uses and aesthetics? If you're getting a TKL, it's a moot point however. Are you a fan of keyboard lighting? You can get one with a diffuser (lit on the PCB itself, with a translucent piece inside the case to show off the lighting better) or per-key LEDs, and even both. It'll be much easier for you to find your ideal keyboard (or at least one you're eager to try out) if you know what you want.
For me, I got a keyboard from KBDfans; they sell the kits as well as assembly services. Their prices are very reasonable for the quality they offer (~$200 or less for aluminum cases+brass weights and diffuser/backlighting, as well as a huge variety of switches), so I'll vouch for them.
