I need to get ahold of a pressure guage for an Astoria Argenta 1 group machine. Could also use an on/off knob & single spout porta filter. If anyone has an astoria laying around that's not working & would like to sell me these parts, it would be much appreciated. Or if anyone knows the best place to buy this kind of stuff (preferrably used) let me know.

Thanks
