I'd look for sales on more expensive ones... I got a pretty nice Bushnell for $98 which was like 40% off
Man I have a HALO as well, so far it's done well for me! Took it to KS last year and compared it side by side to my buddies Leica and they ranged the same yard for yard..... For 99.00, it was worth a try!
Check out Amazon as well. I just got my first rangefinder and it works just fine. I got the Bushnell (The Truth) rangefinder for $142.00 I figured I got a good deal since Cabelas was selling it for $220
I just bought a Simmons range finder on eBay. Most of them are going for about $80-$90 on there. I like it so far. The one I bought calculates for elevation too. It gives you a shoot for distance. They call it tilt technology. Its like the Bushnell arc technology.
