Welcome first off. Secondly I would and did stay away from sets. But if your set on a set purchase an Atlas set might be only my opinion but it is quality all the way from the track to the loco and rollingstock.
But the best way to go is to get a Atlas Snap Tack expansion Pack a few pieces of same code Atlas Flex Track, a Trainmen GP 15 loco and a couple of Atlas Trainmen Cars(Rollingstock), and one Model Tech (DC) tranfomer all for slightly more than a set and much better, needless to say will keep you happier for a longer period without wanting to expand to quickly
Most of all "enjoy it's built rite in."
