Try the RBA. It's cheap and got me into coil making. This way you know what kind of wire you are using as well as the cotton.
Cleaning can be tricky. What I do now is keep and install one of the original Joy atties to make the seal complete. Use needle tip bottle with warm distilled water, into the tiny fill valve, close and shake. Do it twice or more if you like. I remove bottom and pour out water. If you have some canned air you can blow it out. I'd be careful on inserting Q-Tips in the unit as its TIGHT in there. A few drops of water in the next juice is no big deal, but be careful, sloppy job and too much water could find its way into the electronics! Oh and when you shake the cleaning water in the sealed up unit, keep your finger over the air flow hole on the bottom. I tried tightening that screw beforehand, but it's not a water tight seal. Works for me.
