I like skiman762's suggestion - the Fun Fly 90 by Model Tech is a 3D-capable ugly stik design. You can fly it sport style on low rates or 3D on high rates. Hobby People has the Fun Fly 90 on sale this month for $139.99, $30 off the usual price. It should fly great with a .90 4-stroke on it, too.

Another good choice might be Cloud Dancer 60 by Ace Hobby:

The Cloud Dancer 60 is a terrific looking sport plane that would be fun to throw around and would probably be OK as a practice plane for pattern flying, too. You can buy it for $193.99 from thundertiger4u.com and they'll ship it at no charge ($150 or more = free shipping).
