Huh, Stihl dealers won't sell by the roll, since when? Spinner tools there's no need to stock since few buy rolls of chain but those that do can easily get a spinner, trust me I know.
Thinking about rolls of chain I got a call the other day from a fire company wanting a price on a 25FT roll of 36RDR Carbide chain. Only 2009.00 a roll list, now thats costly chain.
As for 3 times the price, since when? Chain pricing is usually based on how many loops you buy. Buy 5 or 10 loops and the price drops accordingly. A 20inch 3/8 cheapie chain at Home Depot runs about 19.99 and I can beat that all day long.
I do agree 100% with the first part of your first sentance though, Stihl is the best chain out there. One of the main things about the Stihl chain is how the drivers run the oil up to the rivets really slowing down chain stretch, something even the best Oregon has to offer ignores. I'd love to have a buck for every Oregon chain brought in by a customer wanting a link taken out because the chain has stretched beyond his chain adjuster. I could buy me a nice saw..
