I got back in the hobby in 2009. I actually did pretty well with busting boxes, but stopped buying wax in early 2011 since these companies (a la Panini and Topps) started churning out these awful products which you would be lucky to break even on. Though, the thing I've noticed the most about people in the online hobby community is that many collectors have no self control. Panini and Topps don't have to put a ton of effort into a product since they know that collectors will pay the $100+ for it, no matter what.
Anyways, I got out the hobby last spring. I enjoyed buying/flipping singles a lot, but it just got too expensive. Selling was a pain in the arse sometimes. You get lowballed by morons on a hobby website, and get nickel and dimed by eBay's fees. Too much of a headache. That said, I'll probably be back in the hobby soon enough.
