The biggest ticket item I have bought with my own money is the Liberator Ramp. It was absolutely worth every penny of the $130 I spent. Then again, I wouldn't shell out that kind of money for a sex item very often. I prefer to save up my points on Eden Fantasys when items are available here.
Value wise, I've got a few things on my wishlist for over $100. Out of pocket, I try not to spend more than $20 or $30 after points, coupons, and other discounts.
I haven't seen anything on EF that is out of my price range, but wether or not I purchase it is based on if I think I will get my money's worth out of the item in quality and time used.
