I've had my Canon Eos 300d for about one year now, and am currently looking to upgrade. Firstly, I'm probably looking about a £400 budget. I'm really leaning towards the Canon 450d, since I've used Canon before and I love their Cameras. But, I'm selling my lens as well as my 300d, so their is no real reason why I shouldn't switch to Nikon... if you can persuade me. Also, I've had an offer for my Eos 300d for £200, is this a good deal? It's hard to judge the worth of a discontinued camera, but Amazon prices are about £260 used. Thanks!
