Any suggestions on where I should go for a new cover? Dealer or secondary vendor?

I have the factory tower down cover. However, I am going to be storing the boat on a lift this summer and we are not allowed to have covered lifts on my dock. Last summer, I had the boat moored and I could see a storm rolling in and wanted to cover the boat. It took me about 5-10 minutes to put the bimini down and lower the tower. In that timeframe, a massive downpour started and soaked the boat. If I didn't have to lower the bimini and tower, I could have had the boat covered quicker.

Anyone have a general idea what price point these covers cost? Thanks everyone.
