I picked some nice ones up on ebay for around 10 bucks for a pair that seemed to work just as good as the high end high $$$ ones. I just looked again and it looks like it's still a buyers market.
I think I paid around $50 for the last custom set for my boat last year at Signs Today in Minot. I’ve had him do my last 4 boats and they’ve all looked great. I’ve even had to have him recut a couple sets from getting a tear or dock rub and he’s always great to deal with. I even f’d up one set installing them and he gave me a new one for free. Completely not his fault but helped me out anyway. Great place to deal with!
Signs Today in Minot, I can’t remember the cost but like SLE said around $50. I scratch my head when some people have a beautiful boat and go buy Walmart or Menards number stickers and apply them on their boat, and sometimes crooked... Lol
