Best place to buy a (music) keyboard in Austin?

i'm thinking of picking up a keyboard with some of my tax return. i took piano lessons as a kid, mostly quit around when i graduated high school but i want to get back into it.

i want to keep it in the $600 range. i'm thinking something like the yamaha p-115, but i want to try out a few different models in my price range to find the one with the most realistic feel.

capital music center is pretty close to me and it seems like they have a pretty good selection, so i'm leaning towards going there. but i'm willing to venture farther afield if there's somewhere with considerably better prices. since i'll be trying out the keyboards in store, i don't want to screw them over and buy it for cheaper online, i'm ok with paying a bit more to get something locally but still want to get a decent price.

any thoughts?
