Been looking for a new t-handle tap wrench, especially one that holds the smaller size taps (like for #6 screws). Came across this on eBay:
About half the price of an Irwin model. Could be Chinese junk (despite, or perhaps because of, the US flag emblem added to the picture) but then, it's a pretty simple device without a lot of large forces on it. The ratcheting feature could be nice for small spaces, and it comes with four metric tap bits.
