I'll deliberately throw another wrench into the mix here
why not forget about the idea of a DSLR and go for a really good bridge camera.
I would obviously suggest pentax to be loyal to the brand and forum members, BUT....
I have used a Kodak DX7950 for years now, in addition to my DSLRs. While somewhat outdated by todays standards, 5MP and a 10x zoom (36-360mm equivelent) the camera can operate in full manual control, has flash sync to external flash, can take front end close up and ultra wide adaptors, and the lens is not slow, but actually quite fast at F2.8-F3.7. WHere else can you get a camera with a 400mm equivelent focal length at F3.7 that weighs less than 500 grams.
This camera is about 5 years old now, and many of the new bridge cameras have optics that are just as good, and much better sensors.
For someone who wants small, light , flexible, a bridge camera is a good bet. the only short coming is that at 26mm (the widest 35mm equivelent I have seen) they are somewhat lacking in wide angle, which I see as a shortcoming if you travel in cities. But that is why I have a .5x adaptor
