I'm thinking of buying my first mac pro from MacConnection. Does anyone have any feedback on customer service from them, good or bad? Are there any other vendors that I should be considering? I'm looking to buy a single Quad 2.8 and they have a config with the 500GB drive for $100 less than buying from Apple with no rebates to deal with. I also considered MacMall but the fact that there is a rebate and less than stellar feedback here in the MR forums has me not wanting to purchase from them. Thank you!
