OLM is in my top 3 list right now. I've heard mostly good things from everyone I've talked to. My first choice was originally Burst.net, they had some very nice packages and outstanding support. Unfortunately, things have been going down hill very quickly over there. Messageboards dedicated to talking about webhosts were highly praising the company a couple months ago, now they're damning them. They're rumored to have hours of down time every couple days.
I think I've decided against Cihost. I just recently was made aware that they have a class action lawsuit being put together against them from a group of former customers. That makes me more than a little hesitant to go with them, especially if they were to lose the case...
