I don't buy Saltiga anymore for that reason since its much harder to service and parts are hard to come by. Shimano however is pretty much guarantee for 10 year of service. After 10 the part might not become available.
For the most part in the east coast there isnt a reason to have stella or saltiga over vs for pier or surf fishing but if im out on the rock and trying to catch a tuna or gt. I'd much rather have a saltiga or stella.
