Agreed, the Tamiya Fletcher is a great first kit.
The Panda Burkes are inexpensive, but they're little bears to assemble. I've never had a model 'beat me' but this one has come awful close. A poorly engineered kit, but for $20 you can't complain too much.
Another good first kit would be the Banner/Trumpeter Arizona, they're rather inexpensive, and a build up fairly well.
There's photoetched detail sets for all of these models.
Good luck, let us know how it turns out!
