VAS (Steven Leung) cartridge repair/retipping service?


Any experience with or opinions about VAS/Steven Leung repair/retipping service?  Not for VAS cartridge.

Thanks!

Steven is a paragon of integrity. I contacted him to fix my Sumiko Blackbird about a month ago. Elsewhere, I have been quoted $1,000 for the retipping. His quote was almost a quarter of that amount. He called me to offer his own cart VAS Nova as a replacement. I had no use for the dull Blackbird anymore (who would pay the grand if a new Blackbird cots just a measly $200 more?). He ships his Nova to me. It gets lost in shipment (USPS refuses to acknowledge it is lost, it simply says "out for delivery" for a month). A less honest seller would have said tough luck, I spent my time and my parts, not my fault USPS lost it. But Steven promptly created a new cartridge and shipped it again at his expense. It is being broken in , but I already hear details I have not heard before even with the $1,200 Sumiko Blackbird. 
Outstanding seller!
 Will never buy or repair a cartridge anywhere else.

Steve did an outstanding job retipping an old Linn Troika a few years ago for me.  I sent it to him and received it back and mounted in less than a week. I highly recommend his services.
@Vasaudio; I see in this thread that you have convert  a Denon 103 to mono cartridges.  I have a Grado Master Reference cartridge with one dead channel, I wonder if that could be converted into a mono cartridge. Would it be a good move cost wise?
Upgrade report:
VAS Steve upgraded VPI scout master motor, JM9 inner wiring in arm and junction box, new VAS Nova 0.4 mv version.

The surface noise is zero to none. Very very quiet. Cymbal sounds very fast, clean, real, detail, like real metal to my ear. Cello sounds woody, powerful, deep, and focus. Vocal voices are very realistic, relax, thick, and present. Channel separation and image is wide, accurate, and 3 dimensional. 
Huge thumbs up for Steven!

I sent him a Koetsu Black Goldline that only played on one channel.

He diagnosed broken coil wire and repaired same and returned to me all within 3 weeks.
I thought price was fair and it now is playing on my 401 like a good un!
