My experience has been good and I’ve never read anything on these boards to suggest that their credit card was cracked via Dreamhost.
Here is a recent blog entry about Dreamhost’s history of accepting credit cards.
I think they’re reliable and have experience only professional customer service. If you read through postings on this board, you will find a few who disagree.
Dreamhost offers you a 97 day money back guarantee, so you have more than 3 months to decide for yourself.
