So I used to shot a lot more than I do and I've just started getting back into it. Since nobody has mentioned it yet have you considered used. We have a place called Henry's in Canada, they are a pretty big chain and usually have a good selection of used equipment and I think they stand behind it with warranty etc. You might get more lens for your budget than going new. Just my two cents.
