HP 2133 netbook, worth repairing? (XPOST from hp.misc)

(I just found this group, maybe it's better than hp.misc for this sort of
thing)

I rececently picked up a very dead HP 2133 netbook.

A little research on the web seems to indicate that these had a pretty high
early failure rate on the motherboards at initial release (must of cost us a
bit for warrantees). The one I have seems to have failed in the
"characteristic" way, the power switch works and the battery charges, but
that's the end of it. I took it apart and pulled out the mobo and took a
look (BTW, the folks that build these must have better eyes than me, and
really tiny fingers or good tools. It took +2.5 reading glasses and jewelry
tools for me to get it apart rather clumsily). There's nothing obviously
wrong like charred traces or broken connectors.

A little more digging around and I found replacement motherboards on Ebay
from around $140 up.

So is it worth trying the replacement? I'm worried on a couple of accounts.
One is that the mobos are graymarket pulls from returned units and so
suspect. The other is that even a new mobo may still have the same
reliability problems as the originals.

Any info would be appreciated.
