Cannot comment on the above three choices. I have Kato Davits and would highly reccomend them though.
Quote I got was 30-40% more with only a 4-1 purchase. Kato offers 6-1 for $70 more. Also changing the lengths was $140 more too. They're also rated at 50 lbs (almost 15%) less than the other brands
Kato makes great quality stuff, but in my opinion....*WAY* overpriced. They have a brand name and know it....they're not worth 40% more than Garhauer which is OEM equipment now on Catalina's, right?
