I bought both the SW 20K and the 8K from Randy at Anglers Pro Shop. Because of the extra spool, I decided to take a calculated risk on the service issue on those two reels, even though arguably, they will get the heaviest wear. (On the smaller Stellas which I will use daily in the bay at some point, I decided to go with American models.)
On the other hand, knowing I would almost certainly have to have the 20K and 8K serviced someday (you wouldn't want to use a reel that I had serviced myself--with all the small parts that would be left over,) I talked to Randy about the parts issue. He is a standup guy whom I have done a lot of business with and know you can trust, and he tells me that virtually all of the parts are interchangeable. I also discussed it with the repair person at Tackletown in Rockport and at McBride's here in Austin, and they can service them. Of course it will be on my nickel, but I made the decision that I am not likely to need service during the warranty period.
