No nasty stories Barra. All I'll say is look at the cost of additional bits you think you'll need now. e.g. additional lenses, macro ring flash etc...
Ringflash:
Nikon £350
Canon £330
Wide-angled Lens:
Nikon (12mm-24mm / 35mm equiv: 18mm-36mm) £900
Canon (10mm-22mm / 35mm equiv 16mm-35mm) £550
Sigma (10mm-20mm / 35mm equiv 15mm-35mm (Nikon)) £335
Sigma (10mm-20mm / 35mm equiv 16mm-35mm (Canon)) £335
Macro lens:
Nikon (40mm / 35mm equiv 60mm) £370 (NB: Nikon don't make macro lenses for DSLRs yet, this is a 35mm lens)
Canon (60mm / 35mm equiv 96mm) £320
Sigma (50mm / 35mm equiv 75mm (Nikon)) £195
Sigma (50mm / 35mm equiv 80mm (Canon) £195
Pretty much everything else can be bought third-party made and the same quality - but much cheaper. So depending on what you want to buy you may find one camera system cheaper than the other. Also, if you haven't already, look at the reviews on
