I bought one of these for my Jallii Flats skiff project. Was impressed with the price. Was not impressed with the instructions, but I have done baystar and uflex hytech kits before so it should work. The nice thing about the home despot card is the 24 months of no interest. I also bought another 15 sheets of 1/2 marine ply (~$150/sheet so more than bolger plywood's $125 1/2 meranti... but its free for two years!):

Uflex makes the mercury branded steering stuff, but the hytech kit was $700? at west marine, versus over $1400 for the same parts but mercury branded. Also, I think the baystar helm is different from the seastar, while the uflex helm is the same as their big one.
Anyway, I plan to use this vevor stuff on my widebody skiffs, with merc 60hps. The main reason to use hydraulic over the 4.2 NFB is that you have a lot more freedom routing the tubes, versus the giant steering cable that needs to have very gradual bends (and thus has to come out of the corner). And also you don't end up ordering 2 different sizes of cables even though you measured everything like 6 times... then losing money selling the wrong sized cable on ebay. Because you cant get a refund for the NFB cables after you open them.
