Hi Clauswe,
I have always wanted one of those 2x2x2 standard circle cubes, it is interesting to solve too. Crazy versions would be fun too, but the standard version would be enough

. I wonder how easy it would be to mod a 3x3 crazy cube/s. (Actually you could just simulate them by getting a black one and temporarily replacing all the edges and centres -of your current 3x3 crazy series- with plain black

).
Cheers,
Burgo.
