I also have the Bushnell Yardage Pro Sport450. It cost $148.98 with free ground shipping from Binoculars.com. It works great for what I need. Has the built in autorain / brush filters. Has a little trouble shooting through weeds, but that's probably to be expected. I've never owned one before this one. So there's nothing for me too compare it to. Here is the link if anyone is interested in checking it out. I just couldn't see spending $250-$300+ for one. I'm glad I bought the cheaper one now. The more expensive ones may be a little better, but this one does the job I need it to do. I also left a product review at the website.
