We don't oversell, and currently one of our servers is a bit on the low-load side of things. MySQL hasn't had any hiccoughs in over five years, and we've got a few heavily-trafficked forums among our client base. Scribehost offers a 30-day money back guarantee, and have just unveiled the new site offerings. However, how much bandwidth/disk space do you need? While it's easy to say, "Yeah, sure, come on over, we'll fix you up" I don't want to promise something that's going to negatively impact the rest of our customers and end up causing you the same grief you've already run up against. (I'm not familiar with your other move-threads, so don't know what specs you need.)

Drop on by or drop me a PM via this forum - or reply with a list of your usual traffic loads, desired disk space/bandwidth/*SQL limits.
