Justin, I dont know if its worth it or not because I have never experienced a 1100 gph. But I can tell you that it comes in handy when time is limited such as afterwork riding, especially when it is getting dark. I have had several experienced riders on my boat and they are always amazed on how fast it fills my sacs.
I have a rule 3800 gph like the one above brand new in box with extra fittings for doing multiple bags for sale. Decided not to use it. Will let it go for $120. Shipped. I accept Paypal. Paid 149 for pump plus shipping. Can email picts tomorrow.
