I don't have any experience with their saddles, but I have had one of their bridles before.
I've found that their tack has all the features that are popular and desired...as well as modern styles and colors. But, their leather quality is very poor. The coloring is basically painted on the top, and the undersides are very rough.
If you can get it for $25 (plus 30 shipping), I'd say go for it. It would probably be a good starter saddle. This saddle retails for $375, so I'm sure the eBay
price will go up in the next 7 days before the auction ends. I personally wouldn't pay more than $100 (including shipping) for a Paris Tack saddle though.
