$2-300 per quarter from affiliate sales from a vinyl record shop that is linked to from http://soundshelter.net

It's completely automated so any time spent on it is time I want to spend (other than a few user queries).

Should really put up some Adsense but don't want to piss of the loyal users.

You could place Adsense if the IP/user/user agent is one you've never seen before (or seen rarely).
