New 650D or used 5d MkII?

[alsocass]

My camera body (1000D) is broken. I took it in to be looked at and the estimated cost is $300. It still works, but it will no longer auto-focus.

So I need a new camera body but I am feeling really confused. I was hoping to look at a new body in about 12months when my photography had improved enough to justify something better.


I am thinking 600D would be the best thing for me - $514 (plus postage). However someone in the local area has advertised a second hand 5DMII for $1200.

I am not sure whether a bit more of an investment would mean owning a camera that I would be happy with for a few more years (I am not the type to want to constantly upgrade equipment, I am not trying to be a pro, I just want to enjoy the craft and have a camera body that gives me lots of options). A few years from now I would like to dabble in sports photography. but mostly I just like doing a bit of this and a bit of that.

If I go with the more conversative 600D, I am imagining that at some stage in a year or so I will feel its limitations and want a better body. If I were to go with the 5D then I imagine it would last me for several years more.

Could I get some advice in this regard?

ETA:
I am doing some comparisons on dpreview, but It am struggling to grasp which is even better! Possibly a sure sign that I should just opt for the 600D (or the 650D?) and return to this question in another year!
