So what am I looking for ??

standard set: PHP, MySQL, mail, good admin, FTP, etc. (Ruby support, whenever possible)

Well, the most important thing is that the hoster is reliable and has a good tech. support Among the domestic hosts considered Agave, Masterhost, Majordomo. But everywhere there is some lack of wealth and reviews about them are also not very encouraging.
