domain Nice brandable name for appraisal

[in_flu_ence]

I am looking for potential sale. However, I would like an appraisal on the domains.

1) e2n.net - element 2 network (very good for internet business)
2) businessfinder.org - All other .ext are taken
3) qef.us - quite easily found (good for local search engine)
4) forumsense.com - Great Forum domain.
Thanks
