I think one of my favorite things about the machine is the Accufeed. Invest in some Accufeed feet for it, you will not regret it! The big harp sure is handy too.
I also recommend buying some Janome-brand bobbins. My machine is not picky about fabric or thread or anything else, but it's VERY picky about the bobbins. I can't see any difference between knock-offs and the name brand bobbins, but I get occasional tangles and skipped stitches if I use knock off bobbins and perfect stitches if I use name-brand.
All in all I don't think you'll regret it at all, and you got it for a great price! I paid a LOT more for mine and I'd buy it again in a heartbeat if mine were stolen or somehow damaged beyond repair.
