I've been at the hobby for a little over a year now, and thanks to this forum and site I've learned what would have taken me years to figure out on my own, I really am glad I picked the hobby back up and picked it up during what seems to be a golden age.
As a semi-experienced, enthusiastic novice, I've come to really like Academy kits. I've yet to have any real fit problems with them, they have nice detail, and they're half the price of new Tamiya and Dragon kits usually. You might also look into Tamiya's line that consists of repressed kits from the 70's. They're usually anywhere from $15-30 dollars (got a Panzer III at HobbyLobby for 9.50), they always fits, have great decals, and as far as I'm concerned have plenty of detail for a novice. They're great kits to cut your teeth on in my opinion. I don't like Revell for armor, yet to do a nice kit... 1/48 aircraft on the other hand, solid value.
Another bit of advice, be sure to pick up this month's issue of FineScale, there is a really nice article on the basics of modeling, what you need (supplies), info on paint, general advice, there's even a glossary of modeler terms in there.
