with Pentax being a good option if more budget-conscious.
Pentax is more the traditionalist option and is the DSLR for people who wish they could still use an FM2, AE-1, K1000.
The big knock against the Pentax is that they don't have the range of lenses that Canon and Nikon do; so if you generally have more choice, especially when it comes to specialist interests like macro, wildlife/sports, etc. E.g. its hard to find a really good 28mm.
"Budget option" also implies that the extra money gets you something that is actually useful and I would be interested in what you think this might be.
