450D upgrade to 550D or 60D?

I'm using 450D, because 對焦 & ISO is not good. I want to upgrade to 550D or 60D, any CHing can give opinion to me please!!
* I won't upgrade to FF & 7D, because they are heavy for me.
* If buy 550D, i think i can buy one more 鏡頭 - Tokina AT-X 124 PRO DX II 12-24mm f/4 II
* 我愛影玩具, 演唱會 ,展覽, 商場

to be honest with you, you already have a great selection of glass. have you consider getting maybe 50D, and pick up  EF-S 10-22mm f/3.5-4.5 USM?

you need 60D

not really, 60D is merely a 50D except with a tilted viewfinder and hd video.

so i don't really point of getting a 60D over a 50D IMO. but i hope you find the right camera that suits your needs man.
