I really cant give you too many options, cuz I havent ridden that many hardtails to be honest. The one im borrowing from a friend right now is the trek 820 series (MRSP $359.99) and from what I can tell, its a great entry level bike. Ive taken it down stairs, off 3 foot step downs, and off small jumps and its held up surprisingly well. the gears are good and I have not had any problems with them, and the shocks have been quite helpful. Trek also has a couple other series for just over $500. I hope this helps.
