This is the bimini I mentioned before on the Cabela's website for ~$180
Cabela's: "Best Value" 3-Bow Bimini Top
It's similar to the River Sombrero (for $240) but the Cabela's "best value" bimini is an imported product, quite a bit shorter (36" vs the River Sombrero 54"), and doesn't come with a storage boot.
If you're thinking about buying a bimini top, my advice is that you don't want it any shorter than the River Sombrero. In fact taller would be even better.
Also, I was surprised at how handy the storage boot is. If your transport your frame on your roof rack (like we do), the boot is really nice to keep all the extra material from flapping and/or tearing apart in the 75+ mph wind.
