We bought a gps from gpscentral. I could not have asked for a better transaction. I orderd it monday morning and it arrived the next day(I only paid for the regular dilivery too). Also, b/c the store is based in Alberta you will not have to pay for any provincial sales tax (still have to pay for GST).
While this might not be the absolute cheapest place to buy (much cheaper than any local stores around here), they have a good reputation.
