I would just get some that look good to you. Do you like Yukon Gold or would you rather have a russet potato or red skinned one. I would avoid the fingerlings for a first try. Those took longer for me. When I go to the garden center or feed store the seed potatoes are usually in a bin and I bag up the amount I want. They are also in the box stores. I don't live in your climate so I don't know which ones are sold where you live. I have never dipped mine in sulfur and they grew fine. Potatoes are easy to grow. You will get reddish bugs which you have to pick off the leaves. My link is Oklahoma advice but look for Okie Dawn's posts; all of them. Toward the end of the threat she tells exactly how she plants them.
