Hi Joe,
I'm not exactly sure on the $150 - but very close to that number. Blue Coral
http://www.bluecoraltowers.com is in Pensacola, Florida and we are in Madison, WI -- about 1000 miles.
They packaged the frame very carefully and we had no dents/scratches/etc. They made a minor modification to the frame that allowed it to be shipped easier (the support arms are hinged).
They did an awesome job on our canvas frame - very professionally done - not just straight work, it actually has a nice style to it. I worked with Roland from Blue Coral - I'm guessing that he is the owner(850-453-0330). Roland followed up with me a few times to see how the install went - he was first reluctant to do the frame without the boat, but after e-mailing them a number of times they agreed to do it. His concern was how close the fit on the boat would be when I installed it -- it was basically perfect fit.
