When it comes to EFI I think you have to determine who can provide the best support then do them the courtesy of buying from them. The cheapest guy on the planet is making his money on volume and likely doesn't have the time or inclination to provide support. The guys providing good support have less time to spend on sales, shipping, etc. so less volume means they have to charge more. When you start comparing prices you'll see that they only vary by a couple hundred bucks. I'd rather pay that extra and have the support when I need it. Rich Nedbal all the way !!!
