I dont do scratch building but i like to build kits. Here are a few places you might want to check out for kits:
Kalteisen - Profiles, some park flyer and some glow.
Stevens Aero - Great little park flyer kits
Ohio Model Planes - Profiles kits, the kit most everything they offer as an ARF
Colombo Anderson - They kit airplanes that fit your budget
The
kit vendors list on the E-Flight Wiki. Most of this stuff is park flyers.
Out of your price rance but they have kits:
Fiber-Lite: They have an Edge kit
Aero-Tech: Lots of BIG airplanes as kits but more expensive
Carden: Again BIG and expensive kits
Good luck with your project.
