Personally I'm not sure it's worth it longer term. 5x3+2 is my preference but I'm doing this to sort my layers so I can try some of the unibody split keyboards that have less keys to go round.
I ordered this on a whim and got a cheap set of keycaps off Amazon for it, but now that I have it put together (plastic switch plate, tape modded, gateron cap golden yellows, double o-ringed keycaps) it is sounding and feeling really good. The keycaps were a cheap but they are bright and fun. I might make it my "throw in a bag and take into the office" keyboard.
