I've amassed quite a hodgepodge of gear. Naturally I always want to upgrade something, I just need help figuring out what I should keep, what I should sell, and what I should buy. Here's what I've got: Canon T2i gripped Canon 50d 18-55 is 28-135 is 55-250 is 18-200 Tamron 28-70 430ex ii $850 debt The debt is from my last purchase, and I have to sell something to pay that off. If I sell everything I'd be left with about $1850 to work with after paying back the $850. I have lots of overlap on my lenses and no particular attachment to anything. What would you do?
