The LMS kit looks a lot more useful to me, since it has a clamping kit and such. Hard to say though, I don't know much about the capabilities of mini mills and such. I'd be worried using a power feed on a small mill with stalling the spindle. I have no idea what your budget is and such, there are some nicer still mini-ish mills that aren't quite mini mills, but they jump up in price quite fast. The G0704 as mentioned above and the PM-25MV and all the variants of it. That's closer to the $2k range though.
