It appears that Klein will no longer be producing this multi tool. The usual places have sold out, and the prices on eBay are $50 or more. However, if you live in the US and want to purchase one, I found an electrical supplier that still has some and is selling them for $19.99 plus shipping and tax. Last night, I bought 3 for a total cost of around $86. I received an email today that they shipping out today.
