Transistor research labs D-225, PRICE?

As in their web there is not any information about this amps, I will be pleased if you can give me the price of these amps.
Also I need to know if these amps are sold directly from the manufacturer or have dealers.

$4500, sold direct. Contact Paul or Brain Weitzel directly via phone or email. They are very responsive. Email me privately if you want more information on performance as I own one.

4k was price quoted to me over the phone in January this year
I'm interested in this model as well

No Dealers at the moment as I understand it

I would give Brian Weitzel a call to confirm
is this for the integrated version or the amp version?
The D-225 is the amp version, the ST-225 integrated is $5500.
