M_Boats: Roller furlers for a Monty 17

Sailors, Asking for input from those that have installed roller furlers on their Monty 17's. What brand do you have and what did it cost? Did you have to change out your forestay to install the unit? Do you like what you have? Did you have to have a special jib made for the furler? Thanks for your help. Fair winds, Tom B,Monty 17 "AS-IS"
