Elan Guides vs. Schweser quality, 2010, difference, december, practice

agulani

Retaking level 1 in december. First time around I used Schweser and am thinking about reordering for dec 2010 test. However, I have been looking at Elan Guides and was wondering if anyone knows why such a drastic price difference? just a new company trying to break into the market? how is the quality of Elan’s practice problems?
I know ill buy either schweser or elan, any guidance on which provider to go with would be much appreciated. Thanks.
