Venus!
My "third" plane is a GP Venus (after my TigerII and GP .40-sized Cap232). I've got about 15 - 20 flights and have seen no bad habits (easier to fly than the Cap, I'm sure). Flys very well slow, but it's difficult to get going slow (especially for landing) because its so slippery!
My best advice is to get the kind of plane you really want. After two planes you should have a pretty good idea of how to fly and the best next step is toward something that you really *want* to fly. Don't go nuts, just have fun. That's what it's all about.
