I've got a caged-ball Record that's still super smooth after a lot of bad weather use with the innertube seal. And yes, it only saves me a littel $$ over the Lizard Skin, but the tube was right there while I would have had to order or shop around for the Lizard Skin seal. Instant gratification wins every time.

Or you could go with a CK. I'm sure they're great and work exactly like they're supposed/purported to.
