i'm using
www.highwirepcs.com unlimited plan. people have been bashing the host on vb.com when i posted it up for a review but i've been with them for just under a month (new site) and they are just wonderful. they are EXTREMELY cheap and very fast too. they are getting a semi-dedicated server so i'm looking forever to more great things from them.
as for the technical support. their support is done by email, support forum, msn messenging, and telephone. we've submitted some support emails to them and within 5 mins we got a reply. we also called them at 10pm (EST), left a message and within 15 mins, a live person called us back. so there is no doubt in my mind that their support isnt amazing.
