As far as brands like Weld-On #3 and Tenax R-7, they're about the same, just "hotter" (Too hot, IMHO), since they contain more MEK, but they also evaporate faster.. Straight MEK itself used to be available at hardware stores, but has largely been replaced with "MEK Substitute" that frankly, I'm not gonna try... I've got about a gallon of MEK still on-hand, as I bought out the hardware store's supply when I heard it was soon going to be pulled off the shelves...
Other than that, I still have the CA and white glue on-hand too.. As for CAs, I only buy the carded 4 tubes for 1.99 typpe from the grocery store.. The "Hobby Shop Brands" are, to me anyway, over-priced and don't have any real advantages over "cheap" CA... The Hobby brands get tossed out because the damn things won't open anymore, well before they ever get emptied..
