Get your First Watt SIT-3 now?


I am just saying this because I found it very interesting.  I just purchased (ordered) a new First Watt SIT-3.  I was hoping to save to upgrade my speakers but love my F7 and read so many great reviews on the SIT-3 that I thought, 'with only 250 being made, maybe I should pull the trigger'.
Well, looks like the right choice.  I trust my dealer, he has always been fair and truthful.  Anyway, he said when he contacted Pass, he was told I got the last one they are producing.  I had already paid for the Amp.  I heard they were making 250 only anyway, but mine is reportedly number 107.  What about the other 143?  Is it numbered in an odd way?  none of that matters.  
I only write this because if it is true and you are seriously looking at getting one, I would jump on it before it is no longer possible.

One more update: Just an FYI

So, I am actually getting number 251.  I spoke with Nelson Pass, however, and he noted I was getting #251, the first in an additional 100 amp production.  SO...if you are thinking of a SIT-3, there may still be some out there to be had.
So now it's September 25th 2019.
I bought a SIT 3 from Reno HiFi a couple of months ago.
They still show them as in stock. 
Mark told me he had 2 more back when I bought mine.
Refined Audio has them as sold out.

Im using the SIT 3 to drive Cube Nenuphar speakers. The line stage is Ed Schilling's The Truth. To me, this is my mountaintop, my grail system. It's way beyond what I expected. I'm done buying stereo equipment except front end upgrades.
For people who might be interested in building a DIY version of the SIT-3:   https://www.diyaudio.com/forums/pass-labs/326536-sissysit.html.  As @atmasphere points out, even the NOS V-FETS are in low supply, but still available.  
Bakoon amps would be worthy of considering as an alternative.Both designers are producing really special sounding and highly evolved amplifiers.I own a Bakoon Satri 5521 which is a wonderful sounding thing.
Here is an interesting review which compares a 15 watt Bakoon with the SIT1 and praises both.http://www.6moons.com/audioreviews/bakoon/2.html
