I was considering the same and ended up building a Kossel mini with 2020 extrusions, 360mm horizontal, 900mm vertical and 330mm diagonal arms.
That gives me a printable range of ~280x450mm.
I'm very happy with the results I get running Rich Cattell's Marlin with auto calibration.
Have a look around; there are many upgrades/improvements available already for KM, just pick, download and print the ones you like.
