I just bought a towerbiminis.com bimini via onlyinboards.com for my aerial airborne. It's a bit of a pain to deal with due to my speaker arrangement but it's of good quality, looks and fits great. I still need to get some pics.
Tower Biminis by far best all around. They custom made my bimini to fit around lights and speakers and where able to make it extra large! The guys there are great! They can make anything! And make it look great!
I have the same tower in the pics (in black). I was able to mount it up a little higher, and chose to mount the straps differently, so I didn't have to drill into anything. I was out all weekend and it worked great.
I have the aerial double speakers. The bimini fits just fine under them. I have to disconnect the front bow as usual but also the rear support arms to fold it. After it's folded I have to reattach those arms and put the boot on. It was a big pain at first but after a few times I got the method figured out.
IMHO mine looks way better than the example above. I'll have to take some pictures the next time I pull it out of the garage.
