MicroFish, I had one of the Berkley 50# scales a few years ago, wife got it for me for x-mas and it fell apart on a summer steelhead on the Columbia. The mistake was she got it through mail order from some place back east and he wouldn't replace it, told me to send it too Berkley.
I,m going to get another one soon localy (GI Joe's, Fishermans) so if I have a problem they'll take care of me. I only have experience with Berkley and I liked it and thought it was easy to use. GI Joe's has the 50# on sale this week for $27.00, reg.$31.99 I think it said, Fishermans wants $39.99 (5/17).
If you don't get replys about the other scales you mentioned I'd be runnin' to Joe's to get a Berkley while they're on sale.
