Blues aren't better for gaming. Some people would claim they're worse (hard to doubletap), but I've been using mine for a few days now without any issue whatsoever. Of course, I'm not a pro gamer and my APM is probably lower than my postcount, but c'est le vie

Browns do have a smaller tactile "bump" as you move the key down, so if you were hoping to have something very significant there, they may not be the best choice, but they're still quite different in feel than a regular old rubber dome keyboard and will last you a very long time without much/any degradation in feel or quality.
While you could get an Adesso MKB125/135B or a Scorpius iOne shipped for under $100USD, there have been a few quality concerns about each posted here and elsewhere. One of those Quality Control scenarios: some keyboards are fine, others are not. Unless you've got a good warranty, it could be riskier than a higher-end brand.
The Razer BlackWidow is in your price range, too, but it's got noisy blue keys and some people (fewer than the Adesso/iOne) have concerns about it, too, mostly in terms of keycap wear (a problem for most Razer boards). That said, it is a "gaming" keyboard, so it's got macro keys and media keys and whatnot. . . that may be a nice thing for you. Definitely doable for much less than $100 shipped.
A tenkeyless Leopold will probably run you somewhere between $110-$120 shipped depending on where in the US you are compared to EliteKeyboards' shipping facilities; if you're outside the US, it will be much more expensive than that. They're designed by the same guy as the popular, well-made Filco Majestouch line and people who've imported them from Asia have had good experiences thus far. I would recommend a tenkeyless in brown when they're available (probably later today!).
The last option you could consider is the Rosewill RK-9000, which is in many respects a rebranded Filco with a US distributor (Newegg), good quality, and a good price tag when it's on sale ($70-$80 isn't unheard of). On the other hand, it's got noisy blue keycaps and has been out of stock for a couple of weeks now with no official word about availability from Newegg going forward.
