There are plenty of fast electrics available at reasonable prices, starting with the Parkzone P-51, FW-190, and F-27 Stryker:

If you want something with a little assembly required, check out the Zagi flying wings from Trick R/C:

If you want a more modestly priced package that's ready to fly, check out the Phase 3 Swoop from Hobbypeople.net:

Dsegal is right in cautioning you, however. The faster they fly, the faster and harder they crash. Don't be afraid to get your own Cessna-style park flyer and get really comfortable with basic flying skills as well as launches and landings before you fork over $250 for a ready-to-fly F-27C Stryker or a Zagi Tazz and a computer radio. A little patience now can save you a great deal of heartbreak in the not-too-distant future!
