Devilbiss finishline/startingline cups the same??
 

I have the Finishline 3 with the dekups system. I would like to buy just a standard 20oz metal cup. Looking online at a few places they are selling replacement cups for startingline series for 20+/- dollars. Are they the same fitting does anyone know?? Thanks!

No, they are different.

I had been looking for a replacement cup and found one that fit.. I believe a generic brand one at a swapmeet or maybe I found an adapter at a hardware store.. Cant recall I'll look at it when I get home
