+1 for the Sig. I have only handled one for a short time but very impressed. Very accurate, precise and compact with extremely adequate glass. Didn't check for illumination. May upgrade from my lrf900 (which has been faultless) as sig pings to several thousand metres.
I've had a quick play with a couple of the Sigs, and they certainly seem to perform better than anything else for the same money on reflective targets, but they don't seem to perform well on non reflective targets.
At the last Roundhouse, they weren't getting any readings beyond about 400yds through the mist on the sunday, but my bushnells were quite happily pinging the targets up on the hill at 1000yds. I've seen similar with trees on clear days. the bushnells will pick up trees out to about 1200yds but the sigs seem to top out at 800.
The flip side of that is that the furthest the bushnells will go is about 1800yds off reflective targets when the batteries are new. Probably down to 1700 as they wear down. The sigs will go out to 2300yds+ off reflective targets.
So, it depends what you want from the rangefinder. For hunting I would go with the bushnells, which are also binoculars. They also do a mile version (mine are the 1600) which should perform better again. If you want them for target/steels, then go for the sig.
As an aside, I noticed that the Sigs don't use an eye safe laser, so I'd be wary if using them for short range work (<50yds) off reflective targets.
