I just bought Big Air at the beginning of summer, love it. It's sturdy/secure, doesn't break the bank, looks good, easy to install (all thought they all are probably about the same), folds down easily, and they're customer service is awesome.
I was in the same situation when I bought mine. For me the decision was made because I called them all and Big Airs customer service was miles ahead. They have everything you'll need, racks, speakers, Bimini, etc. If I were you I would wait a couple months, you will be able to get a package deal (tower, speakers, board racks) for the price of what you can get just the tower for now.
I have a moomba but here are a couple pictures of mine...
Hopefully this helps a bit, good luck in your search.
