bury me in this dress

I’m going to get myself a DSLR for my birthday but I don’t know what to get. Rain recommended Nikon D40 so I read up on it and fount out it has no exposure adjustments. I’m not planning to be one of those who keep on upgrading their cameras. I think being able to adjust exposures will matter in the far future. Unfortunately, my budget is 30K…hopefully I’ll find a good camera for less than that amount. Throw me your suggestions, my photography freak friends!
