New (old) back-up camera

Much as I would love to splurge £8k on a new D3S/D4 and 300mm f/2.8 lens, my head won over my heart and I picked up a 5yr old D200 and battry grip with less than 7k accuations.  It's not going to be stellar for indoor sports but will be handy as a back-up body for weddings and studio shoots and may even get pressed into service for arty sport shots (grainy images or stuck on a tripod and let the action flow past).
