I'm happy to part out - make offers. One thing I WON'T do, is leave myself with a bunch of spare parts that I will just throw away after the filters are sold. Thanks!
(Another thing I won't do, is sell them for $20, lol. I did actually have two offers like that.)
Sorry, but I won't "get" any FX5's. I am not a vendor, and I don't use canisters. Thanks though!
