The New point Loma Mini has been running in the middle to high 300's on ebay. Not too long ago it has gone as low as the middle $200's on Ebay. It even went for $200 on this forum. It is definitely on a rebound. I believe it is a sleeper and its value will only go up.
However, the price on this one was fueled by the fact it was a super low number, Sweet seventeen. I believe if it was a 3-digit number it would have gone for a 100 dollars less.
