I noticed that they don't have as much selection for my Calcutta or Luna. Availability of parts seems to be an advantage for Abu reels.
I don't know if this information has been posted here on the forum, but here it goes. As of 2010, all major Japanese reel makers (Shimano, Daiwa, Quantum et alles) no longer manufacture replacement parts for any of their reels that are more than 5 years old. The manufacturers want you to buy new reels, not use your old ones. This will especially affect those people who own and love their Calcuttas and some other high end reels which, with proper maintenance, can last a life time. So if you see a hot deal on a Calcutta reel these days, think twice before you buy. Some parts are already nearly impossible to find.
No such problems with Abu Garcia Ambassadeur reels. Parts are readily available from a number of sources.
