VAS (Steven Leung) cartridge repair/retipping service?

I found Steve on Ebay while searching for a retipping service for my Sumiko Blackbird. The poor tired bird has been singing rather dull lately. The price Steve gave me was more than reasonable. I sent him a few pictures. He replied the cantilever looks OK, suggested a couple of more expensive options that were just a hundred more. 
I found him on facebook, gave him a call.
Sending him the cartridge next week. Judging by the feedback here his work will be outstanding and the price is just a quarter of what Needle Doctor quoted me.
Not to hijack this thread, I am thinking of switching from a Pro-Ject Phono Box DS+ to a combo of Schiit Mani and Swagman Linear Power Supply.
The Mani gets rave reviews online, much better than the DS+. Is that a worthwhile upgrade?

I have a Benz REF with sagging cantilever.  Since Benz has become pretty much unobtanium(at least in US), I was looking for options for repair/trade.  I saw Harry Weisfield's  reviews of Steve's work on a VPI thread(Steve is a neighbor of VPI).  As a test, I decided to send my Denon 103R to him for modification.  He removed the body, mounted it on a stainless steel plate and added an aluminum cantilever and line contact stylus.  It sounds nearly as good as the REF (at 4-5 times the price).  I had an accident, bent the cantilever; he fixed it and had it back to me in a week!  He has my Benz now, and I am looking forward to what he can do with it.  Highly recommended!

I bet every retipper can upgrade a cartridge designed in the '60 like DL103 (aluminum cantilever, conical tip), but i doubt every re-tipper can upgrade Benz or some other advanced cartridges of today. 

You said your Benz has not returned yet, but you already recommend this vendor, strange. 

I sent my Brinkman Pi in which is a Benz made to that manufacturers specs. Will let you all know how it turns out. His website says, among others, he specializes in Benz.
