Fair enough about hard to find, but if you can find it, you should use it. Expense is relative IMHO.pretty expensive here and hard to find this particular glue.
You spend a fair amount of time building these designs, and if you don't use the right type of adhesive, the results may be compromised.
Adding some cost due to the right adhesive is easily justified when you look at the equivalent retail value of the cabs, and work out you spend no where near that to build the designs...
