Kurt;
Welcome to the forum!
Academy also a couple of M3 Stuarts with interiors. I think there might be a couple of others they have with interiors, too. But their interiors have a tendency to be inaccurate. Still, they build up to look pretty darn good, and they aren't real expensive for what you get. As a beginner, I wouldn't worry about the inaccuracies. Build them up, have fun with the building and painting, and enjoy the models.
Eric (Tigerman) pretty much hit the high points for manufacturers. Tamiya definately builds up the easiest of all of them and has about the best instructions going (stick with their newer kits). They are about the most expensive, though. Dragon has some great kits, but you have to put up with individual link tracks. Not recommended for the beginner (their allied tracks are particularly difficult). AFV Club has some fantastic stuff.
Good luck with whatever you decide upon.
btw; the picture below is of my Tamiya Pz II F/G. It's pretty heavily modified, but was a MAJOR fun build!
