Compact Board for 3d Printer

Hi All!

I would liket to buy a compact controller like:

RAMBo board

What do you think about them?
And should i buy an arduino mega2560 if i choose one of them?

You won't need an arduino. Those boards are both integrated. They are not arduino shields but have the controller integrated into the board. The two boards are very different though. Smoothie is an arm board while Rambo is a more traditional
ATMega board. Plus there are many more all in one boards that fit your brief description of compact. Sanguinololu is smaller than either one of the boards you mentioned. What are your objectives? Do you plan to do dual extruders? Headless printing? Is printing speed a big goal?
