Since I started storing my boat on the lift, I had a snap on cover made to replace the factory 1 piece cover. I have been very happy with the work and quality of a local shop. It is custom fit, of good quality, and was well below your budget. Just a thought to support your local business (if you have one).
Plus, if you have a problem, it is easier to deal with local than to ship and play phone tag.
I also vote Evolution. It is as much art as cover. Fits perfectly and quality second to none. I have no regrets for the small wait or the money.
