THE best hosting company, hands down.
I do gratis web administration for a few small non-profits and acquaintances, and have moved half my client sites over to 20i.com over the past 16 months. Those sites had previously been hosted by 3 other companies over the years. 20i is far and away the best hosting company I've come across with respect to support, pricing, and ease of administration. Support is prompt, thorough, and gets 'er done.
