[WTB] Sony ECM-CG50 (ALPHA version!)

[rawfa]

I´m looking to buy the Sony ECM-CG50 shotgun mic. Please bare in mind that there is a general version and an ALPHA version that can be powered by many Sony products. I´m ONLY interested in the ALPHA version. A new one sells for us$149 (http://www.bhphotovideo.com/c/product/733895-REG/Sony_ECM_CG50_ECM_CG50_Shotgun_Microphone.html).
If you have one for sale let me know.
