Where the hell did they all go? Seems like they used to be quite a bit more popular but there aren't many new ones out there it seems... Started using one at work and I'm hooked except I HATE the feel of keystrokes on it so I'm looking for new ones both at work and at home. Newegg only has a couple and all but the more expensive M$ one look like they're a compromise between a true ergo and a traditional. Where else (reputable) can I find one?
