I don't recommend for anyone to buy Mach3 these days, as it's been unsupported for years.
UCCNC is very similar to Mach3, so it's very easy to use. I think of UCCNC as a "modern" Mach3.
UC100 vs UC400 - The UC400 has two ports vs one on the UC100, so you have a lot more wiring options. It also can run at higher frequencies, if you need them. It's well worth the $25 premium over the UC100, imo.
