I have a Rebel K2 on the way with a 28-90mm lens (crap). In a month o so I'll be getting a Digital Rebel XTi body and a Sandisk extreme III 1 GB card. I will have about $500 (can) left so what should I buy? Heres a few options I'm thinking of: Option 1: Lowepro computrekker AW bag and a canon 430EX flash Option 2: 50mm f/2.5 macro (1:2) Option 3: 50mm f/1.8 and a cheap zoom. Option 4: You choose.
