I have the old all green Fish Cat and it's done very well for me (had to replace the bladders about 10 years ago, but so far so good on these--first ones lasted about 10 years....uh oh). I've probably gotten way more out of it than I put into it. I too am considering something else. Fat Cat is on my radar along with a couple from across the pond. One by Decathlon (high praise from folks over there), but a concern may be customer service as it may take a fair bit time-wise if needed. That said, I'm of the opinion that the best customer service is one that you never need (or rarely) & most folks seem to really like theirs. There are several other VERY high end ones that people like (the names are escaping me at the moment, but they're out of my price range anyway).
