I bought this endpin stand new for $136 (+ tax, + shipping) from Gollihur Music in late spring this year, and have since sold my WAV4. It is in excellent condition. It works perfectly. All moving parts are smooth and fully functional.
Below is a photo of me playing the WAV4 with the endpin stand. The stand is much more sturdy and better made vs. the tripod that comes with the instrument. The endpin stand also gives the instrument more of a true DB feel. You can really bond with the instrument while playing.
According to the Gollihur website, the endpin stand also appears to be compatible with other NS design EUBs, i.e. the CR/EU line. However, please consult with them regarding your specific instrument, to be certain.
The price is $95 firm, shipped to CONUS only. I accept PayPal, bank drafts/certified checks, and for local deals only, $80 cash. No personal checks please.
