You can usually find an X-10 V3 Tube Buffer online at Audiogon or Ebay for around $250 including shipping, give or take $20. If someone is selling it used, you need to know that there is a limited tube life on it for about 11,000 hours or so (when powered on). I also got the best results with it using standard acoustic research cables which you can get at Best Buy. When I tried some expensive cables with it, the sound wasn't as good! The AR cables are very Neutral.
