I have a 40D which is now a backup since I have bought the 5D classic (only about $650-$750 used!). Anyway I have successfully made a 24×36 print with the 40D. It looks ok but you can tell it has been pushed to its limit. http://sphotos-a.xx.fbcdn.net/hphotos-ash3/546833_425314577523697_1340461447_n.jpg. I love my 40D and I think it would work for you if you would like to upgrade.
