<---- Happy Tigershark owner for 3 years. Bought new, mailed card...have beat the absolute living $*%! out of this machine..and it has never failed me. Matter of fact...it paid for itself 59 minutes into its first outing.... and has also paid for a Seahunter, and an Excal.
I'd have NO problem sucking up a $50 service charge for $100'S of dollars worth of expertise if I had to send it in...original owner or not. I think we've been spoiled by Tesoro and the history of above and beyond service they've offered for so long...jmo.
Do the paperwork, have fun, and ask yourself.... "what do I charge per hour in my chosen profession for my services rendered"...and than honestly ask yourself if $50 is REALLY unreasonable....
Just my .2 worth of opinion...
