MacConnection

Hi all,
I am a pc user about to convert to mac. Looking to buy an iMac and a MacPro, I noticed that MacConnection has better pricing and no sales tax to California.
Has anyone had any experience with MacConnection?
Do you recommend them?
Any other seller I should consider?

Thank you,
Cali

Between them, macmall.com, amazon.com, and macwarehouse.com you can find some deals. Amazon often has $150 rebates. the others often have bundles you can get.
