The biggest expense in Electrics is the electrics. Motor, ESC, Battery can easily cost you over 100 bucks, and more depending on what you decide to get. The electric forum is probably the best place to ask this though. You have to decide if you want a foamie (profile plane) or a wood light-weight model, or a fuel - electric conversion.. Prices will vary from about 30 bucks for the foamie (plus electrics of course) to over 200 bucks for the wood models, and everywhere in-between.

Tower Hobbies or Horizon Hobby (both have web sites) (for example.. there are others of course) can give you a pretty good idea what's available for just about any price range. Just be aware, many models come with brushed motors that are not worth using for any decent performance.
