If you have problems, a reputable web vendor should help you out. I had no qualms buying a Siemens Gigaset online (and saving over CAN$150 in the process, from
http://www.dynadirect.com, if anyone cares).
Canadians seem to luck out with the 2100. US list is US$179, while Canadian list is CAN$199 (or US$129).
If you're after the absolute lowest price, then this is obviously still high, but it does show you can hop to a local retailer (e.g. a Sony Store) and buy a new unit at a very fair price. That's how I bought mine.
A web vendor who seems to have a very good reputation is J&R music (
http://www.jandr.com), but you'll need to contact them by phone to get their "discount" price of US$129. A lot of trouble if you have a Sony Store nearby with one in stock.
The lowest price I've heard of for a new unit is from Popular Digital (
http://www.populardigital.com) at US$98 (search for "av2100" to find it quickly). The advantage of Popular Digital over some other bargain sites is that they appear to ship to Canada. I have no idea what they're like, however, or more specifically how well they support their customers.
