hoobbypeople.net have a number of WATTage brand planes.

I have the Jazz classic mono plane, and I have flown it a bit in my street when the wind is not bowig, but I plan to really fly it in a couple weeks at a school. (I am currently building the school, so I have access any time I want, but I need to have the gym cleared of all the stored materials we are using to build the school before I can fly it.)

Most indor planes should not cost you more than $150 to get them in the air assuming you already have a transmiter that can be used with it and a charger.

My Jazz was:
Plane - $30
Reciever $20
Crystal - $6
ESC - $20
Servos - $40 (4g, could save $20 if you use 6g servos)
Battery - $30
Total - $146

I did upgrade the motor to a GWS gear box for a bit more power so that was an extra $20 and got some extra APC props for about $7.
