domain names for sale !!

Another topic

over the years i have acquired a few domain names - all with the intention of setting up web sites , using adsense etc etc. i have decided to get rid of these now as time just doesnt allow me to do anything with them. i have set up a one page web site for these http://www.astoncentre.co.uk in the hope that the site gets found and someone makes me an offer. Question is do i spend money on an adwords campaign or just let it sit there - alternativly does anyone know of a better method to sell these. look forward to any replies.
