I started another similar thread, but with a low budget.
My EOS 20D dream would probably look like this:
WA - EF-S 10-22 f3.5-4.5 USM
Standard - 24-70 f 2.8 L - although I heard there are quite a large number of bad copies in stores, so I would be careful
Telephoto - definitely 70-200 f 2.8 (I would go with the normal version, although if you need IS, then get that one). I would probably add 300 f 4.0 which is around 1000 USD I think for longer reach, or, get a 1.4x teleconverter, which will make 98-280 f4.0 from your 70-200 f 2.8 - when used on 20D it is 160-448 f4.0.. not bad I think. I wouldn't go with the 70-300 DO - it's a small package, but it's terribly expensive - it's on par with 70-200 f2.8 L IS, which is around 1600 USD I think and it's f 4.5 - 5.6 - slow for such an expensive glass.
I heard 100 f 2.8 macro is a real beauty.. very sharp and good, but if you're going with 20D, mabye you should consider the new EF-S 60 f 2.8 macro.
And yes, If you will consider buying EOS 1 series body, then EF-S is not a good path.
Good luck with your choice
