I built the Retren.ch network from scratch in the beginning of August this year. Spent a lot on domains mostly, especially the one letter, N.MP.
The site was not advertised yet on any affiliate forums and such so there isn't much activity as of now.
Currently active and sold along:-
N.MP
DOT.RE
DECREA.SE
The script is licensed by MFScripts, designed customized a little. It'll be sold also, with the permission of the developer.
Reason for selling is the nonavailability of time required for moderating URLs and managing the affiliate system. It's not much but I can't afford it being a student.

Thank you.
