Haha, shweet. That's a good start. 
You could look into the RexGrigg regulator with the solenoid, which is $140 shipped. Add a LPR, a bubble counter, and a diffusor for the whole shabang.
Or the manual regulator is $115 shipped. Same as above, for the whole setup.
Or, try the JBJ regulator. It's cheaper, and many people report good usage.
I just got all my parts this past week, after some research and asking around, and I went with the JBJ. It should be ~$70-80, comes with a bubble counter and I think a solenoid, add a $15 diffusor, then you're looking at $70 left over. You can use another $10-30 to fill up the CO2 tank (assuming it's empty) and you still have money left over to save for the next refill.
