I used to use @Changelly as they had a good rate, but their SBD option keeps disappearing and re-appearing. It's not something you can depend on. But I feel like there has to be a better way than Block Trades. They're so expensive. They would make a lot more money if they gave better rates. When I'm shipping over a thousand dollars and they're taking nearly 100, that's a serious problem. I may as well be taxed on my gains.
