Well that's interesting about the Pentax's - a very good friend of mine wants to buy her first dslr, and being a Nikonite I recommended the D40 or D60 (within budget, especially the D40) Wanted something not too bulky and heavy.
Having read your comments on the Pentax, I'd recommend her to look there as well.
Nikon D200 with 18-70 lens
Nikon 70-300 ED lens
D70 back up (18-70 lens came with this cam originally)
Nikon SB600 flash
Metz digital flash 76 MZ-5
(soo nice to have a Metz back in the armoury - the SB600 rarely gets a look-in now)
Would like the battery grip for the D200, (MB-D200), but the price is extortionate!! Could get a non-nikon version from e-bay, but haven't heard if the gear is reliable or not. Even the Nikon originals from Hong Kong or China are pretty pricey, even though they are sold with one or two batteries. Jessops - £140 for the MB-D200 - way too high!!
