Do you think I am crazy to ....

Sell the following gear:
canon 10d
canon 28-235is
sigma 15-30
canon 80-200 F2.8L

and go for

either canon 30D or rebel xt
Canon 17-40 F4L
tamron 28-75 F2.8
Canon 70-200 F4L

pramod../

P.S:Some time later I will be buying the canon 100mm macro

Get the 30D and the lens setup _ you won't be sorry. Add the EF-S 10-22mm and it'd be my own equipment I have now.

I say keep the magic drainpipe and sell the rest and get 30d and the tamron and get a wide angle later. Won't get too much cash in the exchange downgrading to the 70-200 f4L

I wouldn't sell the 80-200 L. I'd debate whether to get rid of the 15-30 Sigma as well. It's a nice wide angle on the APS-C format. The 30D and Tamron sound good, though.

I second symon: Go for the 30D and keep the 80-200L.
Why would you consider going from a 10D to XT? Why from 80-200/2.8 to 70-200/4.0 ?
(in fact, the only choises that make sense to me, is the tamron instead of the 28-135IS, and 30D instead of 10D)? Just curious for your reason(ing)

Thank you all for the suggestions. The reason to sell the 80-200 is to get a lighter lens I can handle. Also I was thinking 350d because, I didn't want to spend a lot more than what I got for the trade. I am happy with 10d except for some soft focus/back focus. I just want to eliminate that by going with a different body. So is there any thing I would miss if I got the 350d??

There's always a 20D if you don't want to pay more then the trade. There are plenty of 20D's out there for pretty decent prices. I have an XT, love it but I still want more (iso 3200, speed, better AF, etc). That's why I have a 20d coming in the mail.

Yeah, the back wheel for one.... Totally different (far worse) UI IMHO. I'ld say get a 20D if you won't afford the 30D.
Oh, I agree that portability is about the only thing the 70-200/4.0 has on the drainpipe

Sell those ASAP and get the gear you mentioned! (30D or 20D).

I would replace the 17-40 with the EFS 10-22 (to extend the focal range and reduce overlap betwen lenses) and settle for a 20D if the 30D put you above your budget.

I won't weigh in on the lenses, but I will on the body. A friend sold me his 10D for a back up a while back and bought an XT because he thought he wanted a smaller body. Everytime I see him he mentions how big a mistake it was. There is nothing wrong with the XT, its just a different animal. After 4 months hes still getting used to the steps neccessary to access stuff that was much simpler to get to on the 10D. And even with the grip on it, he can't get used to the smaller feel. He's currently shopping for a 20D or 30D.

buy the 30d, keep your sigma 15-30, and canon 80-200 F2.8L. and buy the tamron 28-75.

don't go from 10d to xt.

For one thing, I'm pretty sure you wouldn't be comfortable with how it feels in your hands.

Change the 17-40 with an UWA - Canon 10-22 or Sigma 10-20 or Tokina 12-24.

Moving to XT doesnt make too much sense - if money is a constraint, the 20D is a better compromise.

Also, except for weight, dont change the 80-200.

I would keep the 80-200L if i had one. The legendary magic drainpipe is a collector's item in some countries.
