Thanks Taz for posting. Always 2 sides to a story.
Now to address your questions about the time frame and emails. If the last email you got from him was on 9/23 and he is posting now on 10/7 that is roughly 2 weeks or 14 days. Notice Taz says 8 days with system issues. Makes sense to me that his emails did not go thru to you since you last heard from him.
Taz has been spending a lot of time moving is 09 Racetech and working on the 2010 Racetech, so yes he has been in and out. I also know that his car got moved in the shop so that a friend of mines car could be finished. Apparently there were some personal issues that had slowed progress. I think that was addressed as well in Taz's response to you.
If Taz was going to scam you, why the hell would he send the valve covers to you on time and as agreed? You apparently have no bitch about them as you have not complained about the quality or the price of the product. Good thing guys like Taz are here on RJ so other guys can get a decent deal on a good product.
Honor payments, well that is all opinion. I pay for a membership to this site every year. I feel that entitles me to list and sell my products. I do make honor payments if I feel that I have sold more than a fair amount of stuff and try to give back a little. Each person has their opinion on how or what they should get/give to a free site like RJ. It does not make a person bad or necessarily make them a scammer.
Sounds to me like Taz's story matches up. What I have seen with some of Taz's other dealings, he has been stand up. He was told that a product he was selling earlier in this year was one thing and it turned out not to be. He made good by it and took the blame for not knowing the product 100%. I have never meet Taz face to face but my interactions with him here, on other message boards and thru friends that know him tell me that he is a person of his word and will get you taken care of.
