Cargo Rack Bimini Questions

I am looking to upgrade the bimini on my 2003 VLX and am considering a cargo rack. I have read that most anyone who has one would not get another boat without it. That being said, I know that Z5 makes a quality rack and Monster Tower just came out with one (I have no info. whatsoever on it).

So, my questions are:

1) Are there any other ones to consider?

2) Even though the MT is more a price point rack is it at least somewhat comparable to the Z5?

3) Have any of you put/seen one on an older boat? (pictures would be great if so)

Thanks in advance for all your help!
