You're welcome to order direct if you like, many have and seem to be happy with it. PCTorque is often (though as you found not
always) cheaper, but they're a
really good bunch of people who will really work with you. If you have an issue and are trying to contact Sager, then they may be able to help you try to get in touch with someone there. I don't have personal experience with that since I've only just ordered, but I couldn't be happier with the treatment I've received from Luke at PCTorque. He's been helpful, courteous, and hasn't complained once about my incessant emails. Though I'm sure he's breathing a sigh of relief that my order's finally in.

Compare the sales policies between the two, and see if ordering from PCTorque is worth the little extra to you or not. One of the perks of PCTorque is that if, for any reason, you aren't satisfied with your purchase, you can return it within 30 days and get your money (less shipping of course) back. I'm not sure if Sager has anything comparable or not, honestly I haven't checked their policies.
