To be honest Wilt, what you are asking the OP to do sounds rather elitist, and would seem nearly impossible to verify (no, posting pics from his P&S won't actually tell us much about his photographic potential).
IMO, he/she doesn't need to justify the intent to purchase a DSLR, and it would be much more helpful if we concentrated on giving tips and recommendations on how best to upgrade/what to buy.
To recommmend that everyone buy a dSLR is a bit like recommending that everyone buy a Porsche Cayenne with 6 speed transmission. It is a failure to recognize that some products go well beyond NEEDS, not the potential of the user! We saw millions of folks scramble after the Canon AE-1 after Canon made it seem like "everyman's camera" when a point and shoot might be better suited.
I asked the OP to define their shooting needs and expectations so we could make suggestion about best fit without overselling the Posrche Cayenne. I did not try to JUSTIFY their decision, merely to tell us needs and expectations, to guide them. That is not elitist, it is guiding the buyer to best meet their needs.
I used to NEED medium format and large format. I do not NEED to have a FF camera, the APS-C 40D which is now many year old, meets my NEEDS! I am not elitist in my equipment purchase or recommendations. Maybe the OP only needs a used camera rather than the latest models, saving money by not buying unneeded features.
, but all in all, I feel that the capability of the T3i far exceeds my ability to be limited by it any time soon.
