Ball-screws would be good and with the right nuts will be zero backlash, but, they are far heavier. They would be ideal if building a serious size machine like a 450mm sq print area or more. I recently built a mini-mill with 16mm ball-screws and a 400mm bed, the accuracy is amazing.
Don't forget lots of machined aluminium parts

DC42 - In terms of changing motors and the drive method, the one thing I haven't asked is how you set the movement scaling as it will be different to stock.
What sort of price will the new board be?
