I just found a Tibaldi modello 50 that cost me just under $250 - it's celluloid and it's great!
Otherwise, look around and there's a few of the Omas's which, in my humble opinion, are a joy and a delight to write with, and can be found (not in celluloid) for under $250 if you're patient.

Can anyone recommend a piston filler for under $250? What is the minimum I wouls be expected to pay for a celluloid piston filler?
thanks
