www.costco.ca has the 2007wfp, 2404wfp-hc, and 2707wfp. Of course, you'll have to have a Costco membership, but you also have the wonderful ability to basically bring the thing back to any Costco on the planet whenever the hell you feel like within 25 years of purchase.
Dell products are basically 'relayed' by Costco, i.e. Dell does the shipping, as far as I know.
Don't go into a local Costco looking for most of the stuff on Costco.ca either, if any of the stock is the same it's mostly a coincidence. Dell in particular is only sold online.
Right now, Costco's prices on the Dell stuff don't seem too great, but S&H is included, so... meh. Just a heads-up.
