I need some advice..

I am in the market for a spotting scope but I only have about $325 to spend. I am looking at 3 different scopes

1. Leupold Optics - SX-1 Ventana 15-45x60mm
2. Bushnell Trophy Xtreme 20-60x65mm
3. Celestron 52252 - 20-60x100mm

All 3 have very high reviews. I would like to hear your opinion on them.

Thank you!
