Hi experts, I plan to get my first DLSR, but only got budget ard $1300, should i aim for those Kit set, like D40X, D80 and 400D? I am afraid that without buying good lens I may not able to exploit the best out of those excellent DSLRs... therefore, should I use like $500-$700 (like second hand D70s or D50) to get a not so hot DSLR and spend the rest on a hot lens (like tampron 17-55 F2.8)? really need you advice, thanks so much
