Whats "a little crazy" is how everyone wants everything for free. If I see a good deal I buy it if i see something I think is overpriced I let it go, why is that so hard for other people to do ? If you don't like it and don't want to buy it why comment ?
In my opinion its worth what hes asking for it, hes about where they were at new plus it has a bunch of upgrades which I'm sure were not free to him. It also appears to be in like new condition and not all damaged laying in a milk crate dirty like some stuff people try to sell on here.
That being said if you don't want a used roots blower why don't you try to go and buy a brand new powerworks or jackson racing, oh wait, you cant anymore.
