I'm currently using icdsoft.com for my site's host. They've always been very fast to answer support, they have great uptime (except one time where the ftp was down for close to a month or so, but I had the inbrowser one in the cpanel so I didn't much care), and quite frequently add more space and transfer for free
I'm using their
universal package right now which was great before but I'm about to outgrow it with transfer this month :/
Even so, I still make no attempt to make it a pay site nor have donation gifts. There is a donate button on one page if people want to contribute, but I don't want anyone to feel as though they have to.
I'd also recommend 1and1. I had a site (non sim related) hosted with them for three years, which ended in october. They had this promotion going where you could try out their hosting free for three years. Great hosting, I had no trouble. Only thing was that the cpanel was really slow for me, and set up oddly. But, it was still pretty good otherwise. Looking at what they're offering up now, I think I might move over when my hosting runs out in March.
