My goodness!!!
I just read the 18 pp thread (long read for someone like me who does not know anything about engines except when they go fast and when they don't, or when it's time to call AAA

and of course I won't be able to offer you any technical advice, but what I get from that thread is that this Evan guy is an immature jerk (I'm being polite). Everything was going pretty smoothly in the beginning (BTW, pretty funny remark about using the unhappy poster's Yaris [I won't name her!] as a guinea pig, but I doubt she'd be happy with that idea

) but I almost fell off my chair when I saw the bit about providing him a copy of your DL... SAY WHAT?!!!
In the future, the minute someone says something like
on a thread, do yourself a favor and
WALK AWAY FROM THE DEAL, whatever the deal is!!! 
I mean it.
NOBODY should get a copy of anybody's DL online, WTF?!!!
The fact that he didn't want to take a credit card over the phone is also weird. Unless may be he was on a cell phone? I've never heard of a merchant or a dealer or manufacturer who couldn't take a credit card number over the phone. RED FLAG.
As to the sympathy you felt because he was taking a bit of heat from the forum members, well, that's what happens when you sell stuff online. I should know, I've sold stuff on e-bay before and you sometime have to work real hard to see listings through.
Times are tough for all of us, and since we're in a recession, we're entitled to be a bit more careful before parting with our hard earned $$$, so yeah, he has to work harder at selling the product but on the other end, we do too have to work harder at keeping our jobs lately, so it's hard for everybody.
Some posts appear to have been deleted but I could see him getting angry w/ Ryan at some point, after Ryan said he likes his Yaris as a DD. Can't handle criticism? hmmm. Later on he's telling people to get off "his thread" and shut up?!!! Hmmmm...
The comments left by the posters saying that the manufacturer could eat the cost of the first one so we know it works, were valid.
You are a good person, FrownOnFun, and I hope you get to have fun with your kit once you finally get it put it together on your car

but I'm not sure that guy even deserves your business.
Sorry for the long post, guys.
