Anyone ever ordered from Provantage.com?

For mail order camera gear I always stick with BH or Adorama, but for what I'm looking for, Provantage.com has the best deal out of the possibly non "shady" sites. Never used Provantage before, but checking the seller ratings it seems overall decent and doesn't look to be the typical fly by night bait/switch, etc type of deal. Anyone had any expereience with them?

This is for a Canon PIXMA Pro9000 Printer:
Grand Total,Shipped:
BH: $457.90
Adorama: $434.81
Amazon: $429.99
Provantage:$406.30

While I have never ordered there, here is a god place to read about online stores. If i come across a good deal somewhere I usually check out the seller at reseller ratings.
