I have recently gone with edge-host and have had a positive experience thus far. Great value, features, and support has been great. I've never had an "emergency" situation where I had to have support that minute; however, whenever I see the owner on AIM or ICQ, he always answers my questions within minutes. I think there are other support reps available, but I have never tried contacting them.
So far, Edge-Host has been very friendly and reliable. If anyone has any questions for me (from a customer's standpoint), please feel free to e-mail me at jp<at>whotek.com (replace <at> with @), AIM nintendo8bit, or ICQ 1863204 and I would be happy to answer any of your questions.
If anything with Edge-Host's service changes, I'll be sure to report back here. Hope this helps.
