You gave up on the MaxNC? The Taig is definitely a big step up. I usually discuss with customers what they plan on making, and come up with a list of accessories based on that. Are you shopping for a budget CNC kit for the MaxNC or the Taig? If it's the latter, then don't cheap out this time - get a Gecko 540 and motors that are compatible with it. It can handle a power supply up to 50v.
