I've got a new GR Research X-LS kit available. It has the Sonicaps and Mills resistors upgrades and the standard binding posts. Also included is a complete cabinet flatpack from PeterJ. CNC'd for the binding posts, but it would be easy enough to add the tube connectors and have both options. Everything is still packed up in the original shipping boxes, 2 in total.
$450 for both, plus fees and shipping. Local pickup in the greater Sacramento area is also available.
