Ebay question for raw set builders

For those of you building raw sets, do you prefer the 'u-pick' auctions or do you prefer to buy lots?
I was going to try one or the other as a way to get rid of commons from the 60's - 80's and curious as to what others thought.
I personally have got some great deals on lot's, but as a seller that could be a bad thing. I once won a lot of 25 1971 Topps that averaged NM for .99 cents plus $2.50 shipping, great for me, but crappy for the seller.

My daughter was diagnosed with type 1 diabetes at the age of 2 (2003). My son was diagnosed with Type 1 when he was 17 on December 31, 2009. We were stunned that another child of ours had been diagnosed. Please, if you don't have a favorite charity, consider giving to the JDRF (Juvenile Diabetes Research Foundation)

Depends how far along the set is. Lots in the early stages, pick-ems in the final stages.
