Your first Seventh Circle will cost around $650 because you need to get the power supply and case which are about $400. After that each module will be somewhere between $250 to $400 per channel. Good stuff though. I believe I read somewhere that Geof Tanner, ex designer for Neve, said the Seventh Circle designs were close to either the Telefunken V72 or maybe it was the Neve 1073. He frequents this board so maybe he can comment.
My local gear rental shop tells me they heard the Hamptone and the opinion was that it surpasses the Great River ME 1NV, which is a considerable compliment.
Myself, I am going down the Seventh Circle route because you can have optional V72, API and Jensen Servo sounds in the same box. Up to 8 channels. I figure 4 channels of API for basic drums, 2 V72 for vocals things and 2 channels of the servo sound when you need it clean and big. That's a lot of sound options for the price.
