As a reminder, always buy what you've inspected and handle it yourself when bagging it up.

I bought an RC toy a couple of years ago. The smiling young lady showed the demo chopper flying up, down, and all around. She bagged up a "new" one and of course, I looked it over before handing her the cash. The remote was different and didn't have 3 axis controls. I walked out.

I went to another shop, and when they knew I was going to fly the model I bought, the price was no longer as good and all of a sudden I was looking at a different model than the one we started bargaining over! In the end, I brought home a nice toy, but it was certainly buyer beware.
