Yeah, EK is the easiest option if you want to buy new. Most alternatives involve importing.
Buying used from another GH member will get you the best deal. Although I haven't seen many 55g boards in the classifieds lately.
I have an extra set of lavender wasd and red esc if you need them. I'm sure other do too. But you should definitely throw the keypuller away if you get one. The only thing it's good for is scratching key caps. Actually, it might be good for removing jumpers from motherboards, but that's it.
