For a while now, I have had an irrational interest in purchasing a digital SLR. Specifically, the Nikon D70. The other contender is the Canon Digital Rebel. I currently own an Pentax Optio 555 which I have been very pleased with. But, the siren song of Digital SLRs is very tempting. What to do? I keep thinking maybe there will be some price drops as competition heats up. Pentax is said to be preparing an entry D-SLR of their own. There seem to be a lot of happy users of the D70 over at DPR.
