I have bought a Callaway 300 by reading this article about golf rangefinder from google. The budget of yours will really suit this model. Do not get me wrong, Bushnell Tour V3 is also an excellent product, but it will cost you more with almost the same benefits. If I list it out, you will basically get the same range, slope adjusted feature and laser technology with a higher price tag. You may get more out of Callaway 300 model compared to V3. It provides additional features like the scan mode. Also, the magnification is 6x in Callaway 300 while Tour V3 only give 5x. So, it always up to the buyer what drives him more. If you want to go purely by brand recognition then definitely Bushnell is more reputable.
