I can't see me having a need for 8fps - I barely use continuous drive on my 350D as it stands. The 350D is my first and only dSLR, and I've found the construction of it adequate, apart from some of the surface paint. What does full metal construction give you anyway?
Good point - I've only got 1 x 4GB and 2 x 2GB CF cards at present. I always shoot RAW, which results in 7-8MB files and somewhere around 425-450 images on the 4GB card. I could probably live with 200 images per card, but would prefer more room. I'll ignore the SD/CF aspect for now as it looks like I'll need to buy new memory cards regardless of the choice. Compared to a 60D/7D, they're pretty cheap anyway.
The RAW files for either the 60D or 7D will be substantially larger than on your XT, so you are probably going to want to buy new cards anyway. I now use nothing smaller than 16GB cards.
