Hmmm. Still thinking about this. I'm not sure if the weight would be a huge disadvantage for me. The battery grip hasn't come off my d60 since I've had it, and I've never been tempted to use it without it. I realize a 1D would weigh more, but the whole professional level body sounds really attractive. The fact that it's older and probably not as responsive as the newer cameras is a downside. I'd really want to play with one before springing for it.
The 350d vs 20d question is still open, but I'm leaning towards the 350d. All of the advantages of the 20d are great, from the command dial on the back to the 5fps instead of 3, but I don't think it all adds up to $500. I suspect a 70-200mm f4L zoom would be a much better use of that money.
I suppose it will all come down to which I find a good deal on first. The 20d with every last accessory in romania for only $850 on craigslist sounds like a great deal, I've just got to get myself down to western union and send the money order.
