Not to take business away from Dan, but Mike Adams (reputable dealer of viper parts) is in Canada... I'm not sure how that exchange rate thing works. But Dan may be closer than Mike. Not sure.
Now the part that other people won't like (and this is the pure consumer in me):
If you are going to install it yourself (aka: you are looking to buy on price alone and NOT on the spectacular service of the reputable viper/paxton installers), then I'd take a whole different approach: the internet has made "dealers" more accessible than ever. Call up _any_ paxton dealer and see who is willing to make a deal with you. dealer cost (aka: dealer buy price) is pretty much the same across the board.... so call a dealership that doesn't normally sell a viper paxton kit and you'll probably be able to negotiate cost +10% or better. Cost +3% doesn't make much sense due to credit card costs, but you can probably find someone who is willing to take the 10pts just b/c it is business they wouldn't have had otherwise.
Dealer "buy" price isn't a big mystery. Most people know or can easily find out what the dealer "buy" price is on just about anything. On a paxton, i'm willing to bet it is 15-25pts. so do the math. Velocity performance in TX has been rumored to sell the paxton kit installed for 7.5k (or maybe 8k). I think someone once posted they got the kit for 6.8k or less. It is all the same game in the retail market...
Same reason that when I just bought my AEM, I called a "reputable" dealer who happened to have one in stock. But their bottom-line price was $500 above what I knew I could get it locally for. I had one the next day for less than the make-you-feel-guilty-because-i'm-dropping-my-pants-for-you-to-make-you-think-you-get-a-good-price deal.
Rephrased for the last time: product resale (whether car parts or otherwise) is the same game. If you are buying on price and not value, then shop around.
I don't buy everything from JonB b/c he is the cheapest... he has the best service. I'm willing to pay for that. many other things, i shop on price.
my .02... flame away!
