I'm not familiar with the older Cyberhome products but the danger one always runs with the lesser name brands is, different models can come from different sources. That is to say, the $80 model might be a rebranded Hitachi that may last for 5 years, while the $60 model might be a rebranded model from the dreaded Apex line.
I'm not 100% sure, but from looking on line, I think the one my mom had was the DVD500 that we bought for about $49 from Walmart. It died. It was replaced by another one that died. My experience with Apex was we got one when signing up for some high speed internet service about 4 years ago. It died. It was replaced with one that looked different, but had the same remote, so I assume it was very similar. It too died.
A lot of cheaper DVD players can become damaged from running in small entertainment centers under TVs where ventilation is minimal, but the second Apex that we had that died was in a bedroom being used rarely as a CD player so it should have had ZERO heat issues.
Again, if you can get something like the Philips for $60, I'd be less than enthusiastic at saving $20 for something not of known reliability. I guess I just see that as akin to buying a Huyndai for $500 less than the equilavent Honda. I'm not brand loyal at all, but based on my not super limited experience, I'd stay away from the very cheapest DVD players if I could ante up the extra few $$$.
