personally....I don't quite understand the whole deal of having to own the 'latest/newest' device on the market. Seems like some people need a support group to get help in this area. Get what you can afford and go out and enjoy your camera. Highly doubt you will be able to tell the difference in the quality of you shots if you used a 5D classic or the newer version...same with the 7D or the alleged new 7D coming out.
I'm always tempted to throw some shots in those silly threads wanting you to post your 5D/60D/etc pics that I took with my 30D.
Now back to opening up the new DVD player I just bought...my first one ever. Was tough leaving my VHS machine. :P
