The guy behind the counter said i should bite the bullet and save to get the Canon 400D. Negatives about the Nikon he said was that the 6MP is so low, Nikons service is very bad and their parts arent that easily available.
Megapixel Shmegapixel. Anyone who tells you Camera A is "better" than Camera B simply because of the pixel count is destined to stand behind the counter instead of in front of it buying the kit.
Theres another store selling the Nikon D40 for R4799 and you get a R750 photography class from Nikon. Its a whole day thing from 8am to 5pm.
That's an excellent deal - take it. The R750 training (assuming it's human to human, even if it is on 30 minutes) is probably worth more than anything else.
The 400D is a much more pricey camera in a different league.
Three people have alluded to this now. How is it in a different league? MP aside it's very similar. Search this forum and you'll find lots of debate on this.

What's the importance/relevance of only being able to use AF-S and AF-I lenses with the D40?
I may have the details wrong (haven't gotten my head about all the Nikon jargon yet), but I believe the one has a motor in the lens, the other doesn't and relies on the screw drive from the camera. If I'm not mistaken the D40 doesn't have an in-body motor. This does not mean you cannot use older glass, it just means you cannot auto-focus with it. And if someone is looking to broaden their photographic horizons, learning to focus manually will surely not do them any harm.
You can do a LOT worse than getting the Nikon D40, and if you're desperate to get into the game ASAP and start playing, then I'd say just go for it. Also, don't worry about the 6MP. This is plenty - its more than your monitor can handle (3000x2000 odd pixels). Whats more important is the quality of your CCD and theres nothing wrong with the D40's, for amateur photography anyway.
Not only is there nothing wrong with it, it's one of the last 6MP CCD bodies released, and benefits from lessons learned in all the ones before it, which makes it one of the best 6MP DSLRs out there. In My Not So Humble Opnion
Of course, if you think you're going to grow into the hobby quite seriously, going for something which can let you flex your wings a bit more will definitely be beneficial, and so saving up for something a little better like the 400D Canon
Four extra MP won't allow you to "flex your wings" and the 400D, excellent camera that it is, doesn't offer you anything else that will.
Which brings me to my next point - as has been hinted in the earlier posts, there is something of a war going on between Nikon and Canon users.
And so far two Canon shooters have said go for the Nikon D40....
Problem is, is that whichever make you buy, you are effectively stuck with future upgrades and lenses for that make as you cant interchange lenses between Nikon and Canon (and any other make for that matter) without starting from scratch again, so maybe your choice might depend on who joins you on your photographic expeditions.
If you're on a budget, have no DSLR experience, and you're not expecting your old man to kick the bucket and leave you his collection of superb lenses from manufacturer X, you really shouldn't be concerned about which brand (of in this case two who both make excellent cameras) to go for. You don't have anything to base that decision on, except the price, really. Get the cheapest DSLR you can find, and learn to use it. Go out and shoot as much as you can. Read the manual (over and over) until you know every little detail of the camera. Once you've mastered that camera, and established your style and have a good idea of where you want to take your photography next, you're in a much better position to choose a system for long term investment.
