We get both Gerber and Apex (which is a private label DuraCoat foil) from Advantage Sign Supply. Very happy with the DuraCoat/Apex foils.
Gerber comes in mostly 150' lengths. Duracoat/Apex comes in both 150' and 300' lengths and as both ready to use cartridges and as refills. I use a lot of 300' refills which is a great savings and also means half the roll ends to beware of. We average about 40% the cost of Gerber foils when we use Apex/Duracoat. It comes at a price, however. The Edge has a built in design flaw in color to color registration that is highly effected by how much foil remains in the cartridge. The bigger the difference, the bigger the error. It doesn't matter in most jobs ... but those that are very tightly registered can have X-axis errors of + or - .025".
