Go with the mini. It's only a few parts away from an axe and all of those parts don't even affect performance (on/off ASA+reg is pricey at $80 but a really awesome part). Rails are gashogs and there isn't much to do for it without paying extra. You can get a mini to run pretty efficiently by adjusting the dwell and reg pressure. You can also get aftermarket bolts to improve efficiency but they aren't necessary. Mini is also about half a pound lighter but I don't know if you care about that.
A new rail isn't really going to be any better than a used one. Get the used mini, I love mine and have no inklings of getting rid of it anytime soon.
