Great sleuthing Mark.  I found the parsing error in the code.  This will go live with the next server update.  Should be Monday sometime.

Thanks again.

We have three of these models now.

Thank you for the kind words.  I love working on the site.  Very fun project and a great community to interact with.

Added this now:

I've added the other color now too.  Both blue and red

I've manually added some sales data for them too.

Thanks for the feedback.  You can do Marketplace notifications with the wishlist tool.  Anything on the wishlist will send a notification if someone lists something below the market price.  

I'd like to expand it to ebay deals and give users more control over the price instead of just "below market price" and control over the condition too.  I'll make a note of these for future improvements.  I hope to work on some of this over the next couple of months.
