Major Epoxy Brands compared to Cheaper Alternatives

I am in the heart of pricing materials for my Tiki 30 #200 and although I have worked extensively with West Systems and know that many others have as well, I have a friend who is a professional boat builder who swears by System 3 and another who has used US Composites. After doing some research I found a ton of other brands that are a fraction of the price of West Systems, System 3 or MAS and although I know you get what you pay for, has anyone used a cheaper alternative with positive results?

    Hallo everyone the topic of epoxy prices is never outdated, so I will add my 30 yrs of experience using a 10 gal kit of resin & hardener for $280 here in Florida. Hypoallergenic, and very little blush, but I always sand if it has set up more than a few days. I also use a two component polyurythane paint wthout primer by applying to the hard, but still uncured last sheathing coat of epoxy.  And for all glue joints I use Locktite PL Premium construction adhesive - built a house and several boats in the last 15 yrs, with it.Great stuff, and the price?  $80 for 12 28 oz cartridges at Lowes. I only use epoxy to sheathe the exterior, using 18 oz biaxial cloth. Guys, we're in the 21 c; Wharrams don't need West Sy, or marine ply, or stainless steel screws, anyplace where the wood (dry!) is encapsulated in a coat or two of epoxy...I use Grip Rite coated exterior screws underneath epoxy sheathing, and I only remove screws where I am going to shape and feather with the power planer. While I'm on the subject of building  a ply boat in 2016 (low resale, esp if a20-40 yr old design) l need to address the subject of used sails. There are many quality used sails available, which are suitable for cruising cats - cruising means not much faster than a monohull. (our cross Atllantic time for a Tangoroa was 21 days, about the same as a similar mono...Don't try to compare yours with one of those quarter of a million $ composite showboats, because our thing is to Get It Done and be out there sailing, on a budget - right?!

    Bottom line: its inefficient, way more expensive, and painful, to  glue a wooden boat with epoxy in 2016; save the epoxy for where it is uniquely suited - as a sheathing and laminating resin. Picture it: you now have a gel consistency polyurethane  - construction industry tested and backed by a big name - adhesive, which you can dispense using a large cartridge gun. No mixing! Put a cap on it and set it aside, and it is ready  to go for your next gap-filling,STRUCTURAL paart joint. And Twelve 28 oz cartridges for $80. I have torn apart several parts I glued up 4 or 5 yrs ago, they ended up as splintered wood and hard glue. I got started using it when I read a rave review by a retired chemical engineer. I will never go back to the Gougeon method. It was new in 1975...

    Does anybody out there has experience with the epoxy of the brand epodex? I had an open container and used it with a filler for some repair work. But that was recently, so no long term information yet.
