For flips I like the Nashbar saddles. I only buy them on sale or promo, and don't think I ever spent more than $20. They look reasonably good, are reasonably light, reasonably comfortable, and well made. Perfect for flips.
I just got
this for one of my own bikes when it was on sale for $25. I am surprised at how much I like it. Not crazy about the graphics on the top, but that gets covered when in use
