Yeah, as many times as I've brought it up now, I'd have thought it was common knowledge on here.  I know Don Pfau, Laser and Sapperfire all had quite a few problems with him not following through on parts requests too...
He asks about parts, and then once a price is agreed upon, he asks for a PayPal invoice and then never pays it.  After badgering him for a few days, he'll finally ask for another PayPal invoice.  Again, he won't pay it.  This goes on and on until he disappears from the site for a couple months.  That happened a couple times prior to the incident described above, with a couple different sets of Strutmasters coil conversions.  I wasn't too upset at the time, because I was able to sell them to other members.
