Depends on how soon it's needed and availability. When I needed one, the local distributor had fired the only person who had a freaking clue, so they couldn't help. I found the answer here, so I made one- took a whole ten minutes and I didn't have to drive across town, where all of the distributors are located.

Not on a client's system? How do you think Xantech makes these- Keebler elves? Are we not in the Custom Integration business? It's not rocket surgery- two diodes and a bit of cable. That's all.

And now that it appears to be disco'd, what would YOU suggest? It works, it's cheap and the parts are easily available. I don't see a problem.
