We have had great luck with mailers and door hangars.
Most of 2006 and 2007 we had done a few mailers, a bunch of door hangars, and we started our own neighborhood paper - all with great sucess.
Door hangars and private newspapers deliverd to the homeowners door are the best bang for the buck - the biggest cost is finding a local company to deliver them for you - usually they will charge you a dime a piece.
Mailers on the other hand has had the greatest response - but at the highest cost.
We are switcing to mailing out our own newspaper which is providing us the highest rate of return (just got 4 new listings this week from our 1st mailing). You can see our newspaper on our web site http://www.hqhomes.com
I think the content of your mailers or any other type of advertising is the most important factor to consider.
We have just started our own blog and we are getting 50 uniques a day - I don’t know if that is good or not but it sounds good - check it out @ http://www.hqhomesblog.com and leave me a message.
Thanks,
