My favorite balsa baits by far are the Zoom WEC baits. They have lots of different shapes and dive depths and they are very well made. If you want a top notch balsa bait, this is it. They aren't cheap though. Peepers Baits has a big selection of Zooms, Simmons on ebay does as well.
Also, check out Lee Sisson Lures at sissonsdesignsdotcom, he makes a few different baits, they are very nice and cheaper than the Zooms. The selection is much less though.
I've bought some of the new Bagley's and I've had mixed results. The baits look nice but I've gotten some with crooked bills. If you buy these, make sure you look them over.
For cedar baits, check out Stanford Cedar, TW sells them. These baits are top notch. I have some of the Patriot Shad crankbaits and some of the Razor crankbaits. They don't float as high as Balsa but they are more durable. I highly recommend these baits.
