Nanodrop vs bioanalyzer for library quantification

[k-gun12]

I'm getting lots of conflicting results when quantifying my libraries prior to cluster generation. Recently I've had lots of samples that exhibit the following after enrichment PCR:

By eye, agarose gel shows nice bright band, correct size and intensity for a tenfold concentration.
Nanodrop reads ~10ng/ul
Bioanalyzer DNA1000 chip sees nothing at all, or .1-.2ng/ul
Bioanalyzer high-sensitivity chip sees ~1-2ng/ul.

I'm planning on running all these with a known standard to figure out who is closest, but recently I've read some no-so-good stuff about the bioanalyzer and it's ability to determine concentration. Has anyone else had this experience?

Thanks!

Nevermind.. I found a decent thread with exactly this info in it.
