Welcome to the dark side of the model world. (Nobody seems to know why it's called that, but it seems to be a pretty universal concept! Maybe it's because tanks are in the dirty, old mud and planes are in the nice, clean air!!)
There are a lot of threads on the armor forum that have asked the same question. Be sure to look back through some of the pages and you'll find them. The most common answers are Tamiya's Panther G series, T-85's, and Tigers. They are all great kits. If you want to try your hand at an interior (all be it, not necessarily accurate), Academy has some nice stuff out there. The M3 series and the Tiger I's are pretty awesome and not too pricey for what you get. My personal favorite, if you go by the # of kits I have yet to be built, are the Dragon releases, especially the recent ones. However, a big consideration is that the Dragon kits come with independant link tracks. These usually look fantastic when completed, but they are a lot more work. There are usually 150+ links per side. Some tracks (e.g the Nashorns and Panthers) have only one piece per link, but some (the Sherman's and Kettenkradrad) have two or three pieces per link. It sounds like you've had some pretty good experience with models, so you shouldn't have any problems. I personally like the indy link tracks, but many don't.
AFV makes some impressive kits, too.
If you're wanting to build in braille scale, the best kits are made by Revell Germany and Dragon. (Dragon's are just hitting the US market. There have been a couple of in box and one build review in the armor forum during the past week and a half or so.
As was stated above, the big thing is decide where your area of interest is and go for it. See what you like, find a kit you like, and ask the forum members about it. We're always willing to tell you what we think!!
Hope this helps.
