as for price, i dunno, is the canadian dollar still worth the same as the US dollar?
canon's CMOS maintains a bit more detail at higher ISOs (though in
this it looks like it's pulling in more detail at every level, perhaps it's just higher levels of camera-applied sharpening?)
nikon's vaunted compatibility has more holes than swiss cheese. D40 won't AF with nikon's oldest AF lenses (which use a body-driven screw to power the AF rather than an internal motor like the newer AF-I and AF-S lenses have). and it won't meter with AI or AI-S lenses (which the pro bodies will do, AI and AI-S lenses are even older than the AF types above). and lenses even older than AI type lenses can damage the camera body if not converted to AI spec prior to use (though i don't know if this damaging is only theoretical or if it has actually happened, seems it may be a specific lens to specific camera issue).
recently bought a 55mm Nikon Micro-Nikkor (macro) lens for under $40 for my D50; it's one of the best macro lenses Nikon ever made. Try finding a good Canon EF Macro lens for under $50.
i'd just buy the nikon and an adapter and i'd maintain metering so
for the uninitiated, canon eos cameras can take adapters that allow them to use nikon lenses. you end up in the odd situation where modern cheap canon bodies can use old nikon lenses better than the modern cheap nikon bodies can. the opposite is not true, nikon cameras cannot be easily adapted to use canon lenses. canon can take adapters that allow the use of most lenses, the prime exceptions being canon manual focus, minolta manual focus (which a mount swap can take care of) and 4/3 lenses.

Thanks for replies,
yes, I am concerned with the Nikon AF-S since they are the only ones that will autofocus for the D40x . are AF-S lenses abundant? I know there are quite a lot of EF/EF-S lenses that are compatible with the Canon D400 XTi
And yes we have costco

. and what's cool is that the costco cards are interborder, ie. I can take my costco membership card from canada and it'll work in california
Both the Canon and Nikon don't feature in body image stablizers . Do you think this will be a problem? All the lenses that do come with image stabilizers seem quite expensive.
any recommendations for Nikon Lenses for a beginner?
AF-S and AF-I lenses are abundant for most photo work. all the lenses specifically designed for digital SLRs, the DX line, are AF-S. prime lenses are where nikon is really lagging in updating the lenses, but unless you're pretty advanced you probably won't miss them.
there is one exception. normally i'd suggest the 50 f/1.8 for most cameras, but nikon's version won't autofocus on the D40x. if you are ok with focusing it yourself then you should still get it, it's only about $100 for a new one and it's one of the best optics that nikon makes.
other than that, the 18-250 VR is a nice lens for traveling around. it'll blow your budget, though. you might want to think about the D40, rather than the D40x. bodies are practically disposable on the low end, whereas glass holds it's value and use.
canon just released a pair of inexpensive image stabilized lenses that cover the range from 18-250. however, they're not in kits *yet* (the 18-55IS will be available with the new XSi camera).
