beginner here looking to get into this. $1000 budget. requirements to be met in the budget: Camera body and lens, obviously. Tripod Extra (would be nice...): Flash unit. Is a flash unit a requirement when starting out? I know im going to need one at some point in time... The two ideas i have in mind right now are: 1) http://www.amazon.com/Pentax-Digital-Reduction-18-55mm-3-5-5-6/dp/B0012Q72IY With a tripod. (flash would be bought later.) 2) http://www.bhphotovideo.com/c/product/438940-REG/Sony_DSLRA100K_Alpha_DSLR_A100_Digital_Camera.html With tripod and flash. thoughts?
