I found this interesting....

Can not tell from the photo or description what process they are using
There are several ways to repair stripped aluminum threads
I paid fairly big money in Germany when I blew a plug in the 3.0L 300ZX motor
I watched the Tech do the hole (pun intended) process.
He got every thing out of the way on top of motor to get a good work area for the plug hole
He fabricated a tower fixture above the head ( mototr still in the car)
The boreing machine and cone shaped cutting tool was surrounded by a big shop vacuum shroud
He set that cylinder to have exhaust closed and intake open and fitted a adapter in place of the throttle body that took a 3/4 inch air hose. The shop compressed air was high volume pump
For the boring process he had vacuum sucking and high volume air into the cylinder to prevent any chips in the cylinder
The fist step was just a cone step bore slightly larger diameter then the original plug thread hole.
The second tool was a wider at the top but same at the bottom cone. The third cut was actually a spiral thread cut that matched the pre-made spiral insert.
Imagin a cork screw or worm gear type of spiral with kinda deep threads. Maybe rifle bore is a better description... Thing looked like maybe 1 to 1.5 turns to seat.
The pre-made "insert" already was drilled and taped for stock plug threads and landing area (crush washer type plugs).
With the air blowing into that cylinder the whole time he fitted and adjusted the spiral depth of the head cut twice until it was fully seated.
Final steps were (I assume locktight) some red goop on the insert and in the spiral threaded hole, heat gun for a few pases, thread in the insert and smack a few times with wooden dowel, perfect weld around perimiter of top of the spiral insert....
Tear away all the contraptions, hoses, and stuff out of the way, reassemble the top of the motor, put a plug in and take my money.
I was in the shop less then three hours and back on the Auto Bahn within 28 hours of blowing the plug on a too deep down shift at too high a RPM and boost.
Cost me 180 DM for the tow and 600 DM for the repair and the exchage rate of the day was 1.74 DM per US $1.00 or about $450 total
Not too bad $300 for a "in the car" weld in aluminum head plug thread repair

Beware using ebay for "intangible" items such as service. There is no protection from eBay or Paypal for that.
That was what I didn't understand, how bidding goes w/ a repair. What the highest bidder get's it repaired, everybody else is screwed? Also, that 300Z had a 6.0L motor in it? Too cool!!!

I just found this interesting, I certainly wouldn't condone using this service thru eBay. I was just amazed at the length's people will go to make a dollar.

The best is getting $200 sucked out of your Paypal account because someone reports their checkbook lost

When I was researching my recourse in that matter, I came across the "intangible" items disclaimer. It made me rethink doing almost the same thing, offering vacuum wiper rebuild services over Ebay. I am not protected, and neither is the buyer. Not a good thing either way, and can drive down buyer's willingness to participate.
I guess it's like MarkMoore said, it's cheap advertising. Just look how much we've talked about it!!

As to the ability to edit your own posts, there might be some data associated with the "permissions" for you to be able to edit your own posts. I can imagine that data may be big enough (or cause a performance issue) to cause concern for the long haul. Aging out and removing that data might be prudent.
