can anyone recommend me some new camera gear?

My dslr is going to be 2 years old on Dec. 26. Last year I bought it a 50mm lens to keep it company. I was thinking maybe a new friend might be nice.

Unlike last year, I’m really not sure what I want to try though. I was thinking of looking around for maybe a nice flash, since lighting equipment seems a bit frivolous at this point considering I don’t have a definite space I shoot in. The Canon Speedlite 580EX II Flash seems pretty radtacular, albeit a slight bit pricey for my poor ass…

Aside from my 18-55mm and 50mm I’ve only tried a couple 70-200mm lenses and I don't feel that I’d need them for my own work. I only use them for action/sports photography at work and it’s not really my thing personal work wise.

Any recommendations would be greatly appreciated! I’d put them on my christmas list, but I know it’s not something the fam would go for, and I like to work towards/make my own big purchases myself. Plus it’ll give me something to research! =D

Thanks pals~
