Do people use buyer's agents

[Eric Graig]

I recently read "Out of State: A Practical Guide to Long-Distance Real Estate Investing." It's an excellent book. The author talks about hooking up with a good real estate agent in the market you're interested in but agents typically represent sellers and as such their interests are not aligned with those of a buyer, particularly an out of state buyer who is interested in renting. I've heard of buyer's agents and was wondering whether people use them for long-distance investing and if so, what has been people's experience?
