I'm assuming you're just getting started...? Go for a trainer type to start with, work up to the "nicer" planes after you develop your skills to match.
Try a Sig LT-40 or Kadet Senior. Fairly easy to build(not assemble - build. There's a BIG difference), and the end result flies great if you follow the instructions correctly. There's also a TON of building articles and help available here on RCU.

Just a note on building a kit vs. putting together an ARF.... It's not necessarily cheaper. A kit, even though the kit itself will be cheaper, will actually cost MORE by the time you get all of the necessary tools, various adhesives, covering material, hardware, etc, etc needed to complete it. You will also need some space to build it in, and lots of time&patience. If you just go with an ARF or RTF, all you need is a radio system and engine, and you're pretty much all set. The downside is that your plane will look exactly like the 1,000,000 others out there, you don't get the satisfaction of "creating" something nice from just a pile of wood that's all your own, and you really don't know how well it's built.

A smaller electric (like the GWS E-starter) might be a better way to go, although the initial cost is a bit steep, it's essentially "free" to fly, instead of buying gas, glo plugs, field equipment, etc on a regular basis for a glo model.

If you just want to get started anyway possible, check the marketplace, local clubs/hobby shops and thEbay(or similar) for good deals on used planes on the cheap. Sometimes you can get a whole setup for less than $200 or so, including radio and field gear.
