I have a FX and use it daily - decals , small type lettering decals , keyboard overlays , window parking decals , small batch items ( short run) - been doing a lot of full color prints on heat-press material for masks and hats lately
You could sell it for parts or to someone as a backup - foils don’t usually go bad unless very old and kept in a non environmentally controlled area ( always someone selling them on eBay and
sign forums) - l’ve bought edge 1&2 foils and used conversion end caps to use in my FX with no problem or customer returns -
