In order to use the pricegrabber setting you will have to set your browser to spoof a desktop browser instead of the mobil version. This is the line from
Baffles Touch Pro essentials post
"Change useragent in Opera Mobile to view full websites instead of mobile versions. Info here."
Correct pricegrabber setting should be
RUN=\windows\OperaL.exe
RUNARGS=http://www.pricegrabber.com/search.php?form_keyword=!###!
the last ! was missing in some of the posts, I don't know if it makes a difference but these settings work for me. I have my phone set to use Opera Mobil with the desktop spoof on.
