Hi nickb, Thanks for your response. I was going to get into details, but figured my requirements are so typical it wouldn't be worth the extra description. This is for a standard LAMP-based app with a minimum of graphics. I expect traffic volume to be low for the near future and have no heavy-duty requirements for video and such. Basically I'd like to find an economical service that can scale with my user base.
