Would of grabbed one if I didn't already have one. Very handy to have. I have used mine for many years with great success.
They have changed the packaging on these kits and are clearancing out the old one.
Multiple stores in my area have them (NE Ohio)
EDIT: A note I just remembered. I did have to increase the flow in order for the unit to work the best it can. Simple to adjust using instructions found via Google. Reviews on Lowe's are misleading as it is obvious the operators did not know how to use it properly. (Especially the guy who said he had to put the tip on while the flame was LIT!)
