LeRoy,
My vote is a DCU problem. The "180" is nothing more than a "150" on
steriods.
I am only stocking the 180's as long as they are available. No issues
with them.
My sanyo distributor says that the 180 supply will dry up since it was a
special order
for Toshiba, but then again, he might be saying that so I'll place a
larger order...
