They are nice. I like the long stick out particularly on fillets and in corners. I have not experienced any fogging. I have to replace the pyrex occassionally due to the glass browning around the edges closest to the arc. They are well worth the money. I did initially find that removing the insulator at the torch head was necessary to get the collets to completely tighten up on the tungsten. It worked out well as there is still no exposed metal to shock me.
I bought mine from CK ( I think ) through a dealer. The whole kit with pyrex cup, threaded gas diffuser, screen diffuser, and insulator was around $25 including tax per tungsten diameter. I use them for 1/16" and 3/32" diameters.
