Just signed up with them last week. Really to early to tell. First impression: speed fine. support is ok. Don't really seem to want to do too much out of the ordinary for you. If you find what you need in their "off the shelf" packages you will probably be happy with them. Other folks I have talked to seem satisfied with the service.
In the last week I have had a few trial accounts set up at CF Networks, Indoglobal and Smartweb. So far I have been most happy with CF Networks and LunarPages. This mostly due to the robustness of the packages. ASP, PHP, and multiple FTP accounts. Lots of tools.
