>>What is your current favorite penny auction site, and why?
Well I havn't been too active at any of them right now. But did watch and participate a bit in Zluxebid beta.. I like their layout and is probably the fav right now 
I have not been active lately either. I would have to say Quibids like BabyF for the true buy it now and huge selection of items. Also, I like that there are not all the same folks, and you have to change up your strategy quite a bit to make it fun. They ship quickly, and are dependable. I don't think they will be going under any time soon so it is also nice knowing there is stability.
