Have you thought about eBay?
I recently sold my 350d on ebay with 18-55 lens, 4 batteries, lowepro bag, filters, and a couple of memory cards for about £190. It took very good photos, and this would leave you with £300 spare to buy other lenses – such as a 50mm f1.8, a zoom, etc. In a few years she may want to upgrade the camera, so better to get some decent lenses
But if you want to buy brand new, then that is a very good deal
Also check out the canon outlet on eBay – they sometimes have some cheap deals on there – all with 1 year manufacturer warranty.
