I need advice on what camera I should look at purchasing in the DSLR models. I have cameras for over 35 plus years, both SLR and P/S. Most recently an Olympus P/S. Ready to upgrade. Most photos are during travel, vacations, around home with friends, sporting events, etc. Have looked at Nikon D 60 and D90 but open to suggestions based on above as well as lense specs. Thx.
