I have a spare transom mount HDSI here. I can send or post pics if wanted - I just decided I should have a spare or two around.... I would do $160 TYD if you can't find one locally for less. I don't have paypal and take money orders or a personal check with 2 week hold for bank clearance. You could use Michigan-Sportsman.com or BBC for people to check on me as a reference if needed.
