We have finally moved into the 21st century and have a really nice classified ads section on the main SDR website.
We put a link to it on the forum main page so you can just make a habit of checking out the new deals when you finish checking out the latest forum post.
These classified ad postings are on the Main SDR site, not on the forum!
Why don't you jump over to the main SDR site and try it out now?

Just click "Classifieds" in the end of the description line.
