You never really know for sure whether your price is too low or too high. You never know when just the right buyer might show up. Sometimes I see saddles that are great deals fade away without any bids, and sometimes something drastically overpriced will find a home, probably because it's exactly what someone's looking for.
That said, I suspect your price might be a little high. You're asking more than the new saddles are listed for.

Here are the completed listing for the used Collegiate saddles, so you can see what they've sold for. http://www.ebay.com/csc/i.html?LH_It...mplete=1&rt=nc
Aha. I just realized you have all the other goodies included in the same listing. If it were me, I'd split the items out into individual listings. There's a good chance that the person looking for that saddle doesn't need boots in that size, or maybe doesn't need any of the other items and doesn't want to pay extra for things they don't need. List them separately, then mention in your listing that you have other related items as well, and that you'll combine shipping for multiple purchases, and I think you'll get more takers. At the price you're asking, people are also going to want to be pretty sure about the saddle fit. You may want to include more measurements of the gullet width and the tree width for starters. Lots of good threads on this forum showing you how to do both.
Have you tried your local Craigslist? It seems like saddles sell for more on Craigslist, because people seem more comfortable paying more for something that they can actually inspect, touch, handle, before buying it.
I hope you haven't taken this as critical. Just trying to help you out. It's a lovely saddle, and you should do quite well with it. Good luck.
