How about between the Twin Air and the Hobbistar mod shown in this month's Model Aviation? I think the Seagull Dual Ace COULD be an option, but I know nothing about it.

I am eventually wanting to work my way to a TF Cessna 310 or some other really cool twin-engine. As far as building those two birds, I am comfortable either way.

This would not be in the immediate future, due to school, but perhaps a year down the road or so.
