I bought my HDLoader from consolesource.com. They're okay I guess considering I got the item, but their service is terrible. They never answer the phones (always busy or the phone rings over and over) and they don't respond to emails. I wanted to cancel my order just after I bought it, and over a week after I emailed them, I got an email telling me it shipped. They never replied to my request.
Anyway, don't buy from them unless you're pretty sure you won't have to deal with their "service."
