Ebay CNC Motor/Driver Kit - Please recommend one

[glynster]

Thank you Neil, that seems like sound advice, being very new to this, I assumed that I had to buy them all as a kit or run the risk of them not being compatible with each other. I am not sure of what particular metrics/ratings I need to be aware of to judge compatibility. My plan was to get a kit simply to avoid those hassle as the mechanical elements have been challenge enough. I do like the idea of upgrading the motors but those stepper drivers seem awfully expensive - are they really worth it?

Would something like this kit from cnc4you be a big step up from the ebay kits then? or just a very slight improvement?

If I did go for buying things separately, is there a halfway house with slightly more affordable drivers? I do think the motors from cnc4you are a definite upgrade and I am sold on that but are they not worth it without the expensive drivers? Also the BOB list you suggested, are you suggesting that any of those will work? Are they fairly universal?

Thanks for your input - much appreciated
