Per Zephyr, sounds what you are looking for is along the lines of her Jamis Komodo, Kona Shred, Transition Bank or PBJ, etc. Unfortunately, all of those have ‘evolved’ price-wise into the well-over-$500 range. In the used market, watch for bikes like Specialized's P-series (P.1, .2, .3, .All-Mountain) bikes, Kona Scab or Scrap, Haro Escape or Transition Trail-or-Park. But beware - - all of those have probably gotten some pretty hard use and may be near the end of their useful life by now
