Hard to beat the Kistler KLX and in your price range. The KLX also uses the North Fork composites blank from Gary Loomis. The only thing I have found that is more sensitive is the Kistler Z-bone
Don't think that the blanks that Kistler uses from NFC are the same blanks that NFC uses to make Edge rods. They are not. If you want a really sensitive rod then get a Edge. Of course you're going to have to come up with a few more dollars.
NFC builds three levels of blanks for the public and then they build OEM blanks to spec. If I wanted to build $100 rods I could buy blanks from NFC if I had a large enough order.
In other words don't get hung up on who builds the blank.
