That's what I've heard about the Radarchron- not to bash the product, but all complaints I've heard are about innaccurate readings and not very good consistency from shot to shot.

You can get a Chroney Archery Chronograph w/ light kit for $105 on the interent. Ok, so it's not an Oehler, but it is very reasonable in price, comes with the lighting kit so you can use it indoors or outdoors. I have this unit and it does give decent readings and consistency. One thing I have noticed is that you need to be careful on very bright, sunny days that the sun doesn't go directly into either gate sensor area. Other than that, it has been a great tool for the money.
