The best bang for the buck is the UScomposites 635 thin resin system. It runs around $65us per gallon. It has a 20minute pot life, but i have used small batches of it for as long as 30 mintes.
I looked into getting this or similar version of it here, comp store has System 3 stuff but just to get a pint kit is $60 plus taxes!!, so i will try my Z-Poxy and see how it does as System 3 resin is just too expansive to get in such small quantity... I don't need a gallon of it either, so lets see...
