I think that would be a better bet in that price range. There are a lot of decent entry level hardtails out there.

Rode one of these for a couple years and it never failed. Actually rebuilding the bike right now as a ss. Pretty decent bike for the price. Very solid frame.

Also might want check out something like the Specialized Hardrock. Another decent entry level hardtail from a bit more reputable manufacturer.
