Here is a much less expensive option that works just as well...
Normal size gas lenses for 9/20 http://www.weldingcity.com/tig-torch...or-wp-9-20-25/
Normal size cups for 9/20 http://www.weldingcity.com/tig-torch...torch-9-20-25/
Large gas lenses for 9/20 http://www.weldingcity.com/tig-torch...or-wp-9-20-25/
Large cups for any size torch including 9/20 http://www.weldingcity.com/tig-torch...-lens-53n-57n/
I use a standard gas lens for everything I tig with either a #5 or #8 cup. 3/32" 2% lanthanated tungsten will do most jobs. For thick aluminum I switch to 1/8" 2% lanthanated.
I like the CK wedge collets much better than standard ones and they work well with the generic gas lenses above.
Here are a few pics of my torches. The first shows the difference in CK wedge and standard generic collets. The second is my CK 130F with a generic gas lens assembly from weldingcity and a switch that I added to the handle. The third pic is the torch that came with my 250EX (never used it), a CK 210 with generic gas lens assembly, a generic #9 with gas lens and the CK 130F from the second pic.
