Ya, I paid $30 for my Potters back in 2004. This when when my LFS just got their first one in and didn't know how it was going to sell so they sold it at cost. After mine died I went back to get another one and they were at least $75. Definately jumped in price. I also read they are not very hardy angels but from my experience and everyone I have talked to with first hand experience that doesn't seem to be the case. Obviously I can't say that is true for every Potters, or even say every Potter will be perfect in a reef but I have had good experiences with them that counter what I have read online.
