Supratek or Don Sachs - which way to go?

Hi everyone - 
Remember me? I'm the OP. I REALLY APPRECIATE everyone's comments on this thread. I am still learning and appreciate the discussion here. 
Frankly, I'm still on the fence about which of the two preamps I'm going to pull the trigger on. Mick's lifetime warranty is really cool and is a testament to his faith in his products. Having said that, living in the PNW in the US, Don Sachs is practically local, so shipping (should it be required) would obviously be a simpler affair.
I retired last Friday. This preamp is going to be a (notionally) final upgrade for my system. I think either one will be a wonderful change to my system. 
Thanks again - I'll post the results of my decision on this thread and my impressions of the new equipment when I get a chance. Still awaiting a final thumbs-up from SWMBO.

Product purchasing decisions based on manufacturer proximity and convenient shipping. That warrants a new thread.

OP: have you listened to either preamp?

”I often recommend products that are not my own (as seen in this thread) [D. Sachs] and would be happy to recommend yours [Supratek’s] as well, provided I don’t have to worry about someone that took my recommendation getting mad because a fire or shock hazard was present in that equipment because a component came loose in shipment or the like.”

You don’t engage in this behavior in other threads. So I ask why now?

@celander

If you PM or email me I would be happy to answer that directly.

Old potentially outdated information, but as I remember from years ago, when Suprateks needed warranty work Mick would decide if he needed to repair the item himself in Australia or if a tech local to the owner could fix it at Mick's expense.

Feel free to correct.

@jetter: Your memory serves you well. I read that here in one of the Supratek threads.
