Stan, here is one that is a couple of blocks away from our house:
http://www.realtor.ca/propertyDetail...dKey=478419328
http://comfree.com/2-storey-for-sale...alberta-297676
Note that the MLS listing specifically lists comfree as the realtor and if click on it it goes to comfree site.
I'm sure there are many others, if you look carefully. According to Comfree site you can have your listing shown on MLS for $299.
I agree that a lot of people listing with comfree are asking too high of a price but if you know the market value (which is not hard to find out) and do a good job of showing the house and (this one is the most important) the market is a sellers market you'd do quite fine. I know quite a few people who sold back in 2007 (the boom) above asking price in less than 2 weeks with comfree.
