Sent you a PM. Call your local bait shops wherever around the lake. Buy six reels in one pop you can get good prices on them. If you are not fishing for a living then less expensive ones can get you by without issue. Been doing this since the nineties and can tell you that I wasted more money taking the less expensive route than it would have cost me up front.
Not being a prick, but if you can't afford 6 reels you should not be trolling. Gas alone this year is going to cut into the trollers pockets. Trolling is a pay to play thing. You dump alot into this in the beginning but the reward is worth it!
