Thanks to gradient for his input. 

I checked with Hannspree pre-sales and got this answer ...

After doing some research, our techs have advised that the Panel for
the HF237HPB and the HF229HPB have the same panel. Both panels
display color gamut of 72%.

OK ... given that it is a refurbished 23 inch widescreen LCD HD (1080p)
monitor with 72% of NTSC color gamut ... for $146 (no tax; no shipping)
... is it a bargain ... or a dog?

BTW, I already own a Spyder2express color callibration device. 

Comments, please.
