Yep, I've worked with DropnZone
I got a set of wheels (Atomlab Trailpimps) through DropnZone over a year ago and Alan was great to work with and offered me a great price. I actually had an issue with my rear hub not long after getting them and he took care of it for me right away (replacing the hub entirely) and got me my wheel back to me within a few days after receiving it.
Also, I have a buddy that just got a Yeti ASX from him two weeks ago and he also received a killer deal - plus Alan had it for him within a week. Based on those two transactions, I'd personally recommend him. Just beware, the guy will talk your ear off....he loves talking bikes!!

Seriously though....it's nice talking to a guy that rides and is as enthusiastic about bikes as we are!
Cheers,
