Hi Jay,
I think you have a pretty good starting point. Go with it and see how your pots sell. If they don't, lower the price a little. If they sell faster than you can make them, raise it a little.
When I first started, all of the pots I made for the first year or two wound up as gifts. When I started selling them, I put dirt cheap prices on them and gradually raised them.
When making one of a kind pieces, I think it's perfectly acceptable to price them based on how good you think they are. I often do this with my raku pieces. Keep in mind: just because you don't like a pot, doesn't always mean much. The potter I apprenticed for has a saying: "Somebody's mother will love it". You'll find that just about every pot you make will sell eventually, it just needs the right person to find it.
Best,
Kevin
