Opinions on these lenses...

I'm basically an SLR n00b, and am considering getting into it thanks to my 21st birthday present from the family. I am looking at the 350d or 400d, as my uncle has given me a couple of canon lenses from his old film SLR to get me started.

My question however is are they any good, and how much would I have to pay to get something better?

SIGMA UC ZOOM 70-210mm 1.4-5.6 Ǿ52

SIGMA DL ZOOM 35-80mm 1:4-5.6 Ǿ52

Cheers. The Lenses are EF autofocus. Any way I can get a rough idea on what they are like based on the spec? The numbers mean nothing to me.
