The TwinStar is an excellent first twin, except for no longer being available.
The Duellist 2/40 is also an excellent first twin for flying, but I don't recommend it as it is not a beginner's plane to build. If someone claims to have lost one due to an engine out, the real reason was something else, as it is an easy plane to fly on one engine.
The one I do suggest as a first is the Twin-Air, from Northeast Aerodynamics. It is an easy build, and seems nicer than the Duellist on one engine. But the Duellist is the better aerobat.

Enjoy your twins.
