Using graduated filters you would still need a tripod for general landscape photography due to needing a very small aperture to get depth of field (therefore slow shutter speed required). Although I've heard the D80 is quite good with high ISO shooting so may not be as big a problem as with other cameras.
I would post these sorts of questions on a photography website to get some good answers.
Thanks for the detailed response John. It was mainly clothing bargains I would be looking at. Millet clothing has got some good reviews in the magazines if I seem to remember correctly, so may look into some of their gear.
In a couple of weeks I'm going over to Calais to the big shopping centre (citie europe I think). I know there is a big sports shop their and was wondering if anyone knew of any good bargains to be had in their ?.
