Wanting a Corbin seat

[Wanderer67]

I am looking for a reasonably priced (used) Corbin seat for my 2014 TTSE. There is a used heated one on Ebay but it is $800.+ and I am just looking for something more comfortable and stable than the stock seat. I love how the bike feels but I feel the seat with the gap makes me feel like I'm riding between the cushions on the couch and I like longer rides (500 miles a day) and feel this will be annoying soon.
If anyone has a line on one I'd appreciate hearing about it. I wouldn't mind a price range around 300 and I know that's a low price.
Thanks to all!
