Actually technically i don't have a budget, but i do have a b-day approaching and the family wants to get me something photography oriented, but they've laid down a max value of roughly 350 or below. . . with that in mind i'm trying to decide between a few things. Right now my setup is an XSi with a tamron 17-50 and a 580 EX II. I shoot a lot of things, but I am getting more into portrait photography as well as outdoor low light events (marching bands especially). I'm split between a portrait grip, a better lighting setup, just getting an OC-E3 type cord or PW to get my flash off camera, or a better lens- most likely the 85mm 1.8. . .suggestions?
