I bought a 14g kit from Wal-Mart (no pump or bubble wall included). Paid about the same as you, I believe. I ended up spending $100 for a better light fixture, $40 for a good filter, and $15 for a better heater. Kits usually have 2nd rate hardware.
I really should have waited and bought something used. I've picked up a 55g tank with stand for $50 and a 30g with stand for $50, too.
