Toshiba gives us less trouble than anything we sell
or have ever sold.
I've had only one Toshiba to fail in warranty in
over 2&1/2 years. I've had 4 Hitachi's in that same
time frame, and that's not bad either considering
the hundreds that we sell.
But, I constantly have RCA's in the shop.
About the only time I see a Toshiba is when
Lightning gets them.
But anything below a 31" set is NOT built by
Toshiba, and we don't sell those.
I think that they should abandon the small set
market, just because they aren't up to Toshiba
Quality anymore.
IMHO
