So I have been having some good luck with Backpage.com. They let you buy features ads in your category that get shown at the top for every search. They cant get flagged for spam so they will stay right there at the top for as long as your listing is active. It depends on your niche, but for me it was a couple hundred bucks for a year. Not bad for whole site, nationwide. Anyway, I'm looking for other sites that will let you do that. Posting on Craigslist doesn't work since any advertisements get taken down quick... It does not look like Kijji has a feature for ads... Any other recommendations?
