I don't see the 5DII as enough of an upgrade over the 5D, unless you 'need' the megapixels. There are some nice features, but I kept mine through the 5DII and just recently got one of the discounted MKIIIs (that is a HUGE upgrade).
Glass is a better investment at this point. I have the canon 85 1.8, and the 135F2L. The 85 is a great lens. The 135 blows it away. Currently under rebate for less than $900...buy two! Excellent headshot and portrait lens. Just stunning.
The 100mm macro is an awesome lens as well, but i'd get the 135 for portrait/general work. If you want to do macro, get the macro. (I have both).
What abou 1ds2? Maybe it is better upgrade than 5d2 ?
I don't really know much about it. It has 1 series features of the day, but its an older body, lacking a lot of features of today's cameras (nice LCD, higher ISO performance, etc)....save up and get a 6D or wait for refurb 5DIIIs....the problem with the 5D original is that its so darn good its hard to justify an upgrade!
