Anyone had Astech mod their seat?

Hi everyone -

In researching options for getting a cushier, long-ride seat upgrade, I ran across Astech who does custom seats as well as padding replacements on stock or other custom seats.

I couldn't find any threads here on them, but there are some fairly favorable reports online about the results of the padding replacement. Considering that the cost is less than half of a Corbin (or 1/3 of a Russell), I wanted to double-check to see if anyone here has done it.

Thanks,
Matt
