For some reason my local Asian owned produce market carries organic
ones at prices similar to what Safeway and other supermarkets charge
for conventionally grown. Go figure.

The organic ones taste even better, IMHO. I limit my intake of regular
potatoes because of the extraordinary number of pesticides used on
them. When Parents' magazine, a very mainstream publications, suggests
you choose organic potatoes, green beans and spinach for your children
because of pesticide residue issues, then you know it's not just a
wacko's complaint. But YMMV
