I'll second the Polecat notion. Of the prices I've seen advertised here, not sure you can beat his dozen price. Add in a spool of #6 Loctite and some "discount" noodles from Wal Mart and you're in business.
Sorry Jer', I like the pool noodles when compared to other floats. But they gotta' be the real big diameter ones. The standards ones don't cut it.

PS
Need a spool of 5/32" bungee next time you're in the area.
