Use www.froogle.google.com . Click on "low to high" for lowest prices first. If possible, use a five star Yahoo merchant that will have full USA warranty and include factory accessorys.
I just bought a Fuji S5000. This is a new model and I saved 20% or $100.00. Also through another froogle site, I bought a whole bunch of memory and saved a bunch of money.
Good luck on your search.
So now you want a Minolta Z1? pcrush
I know nothing about this dealer but first, decide on a camera and then look for a good dealer.
BTW, I did not see a US warranty at the above site.
