I used SR a year or so ago (maybe 2) before the take down and I just need a suggestion on a new market. I was looking at the comparison chart but it wasn't making a whole lot of sense to me... I was also using dwolla and mtgox for BTC so I guess that's out now to.
Evo and Agora seem to be the top two markets ATM. As for buying bitcoin I'd say use LBC or Circle.
