Supratek or Don Sachs - which way to go?

I'm preparing to replace my SS preamp with a tube unit and have read with great interest many threads on this board. This is where I learned about Don Sachs model 2 preamps. They sound like what I'm looking for and those who own them consistently express their satisfaction with them.

Now I've just been reading and learning about the Supratek lineup. Wow. These also sound like fantastic works of art. Leaving me with a new question about which way to go. 

Thoughts? Advice? Experience? Anyone care to share?
