You're not going to find a better 6SN7 preamp than the SP14 from VTA. You can buy it either as a kit, or preassembled and fully tested. You can even get custom builds for a bit more cash.
Complete kit is $950
Fully assembled & tested is $1450

The base SP14 looks pretty plain, but some of really don't care. Don Sachs will do a custom build for you of this preamp. Pricing will depend on just what you're asking for.
