I bought a Leica LRF600 second-hand from an SD site member. It's excellent and I can highly recommend it. You might want to advertise a "Wanted" for a rangefinder in the Classifieds section and see what comes up?
I don't tend to use the rangefinder a lot, but when you need it it's invaluable. For example, last Friday I used it as I was out with a client and we were visiting a piece of our ground that was new to me (I don't personally 'own' the permission, I am a retained stalker). From the tree where we stood to the woodland edge I could ping the distance at a shade under 200 yards. Knowing the capabilities of the client, this then allowed me to identify where the deer needed to be before a shot was feasible. I have stalked this ground for the last 10 years but not this particular field, so having the rangefinder took away any guesswork.
Would it be worth buying a rangefinder just for this, no, but it does serve as a useful example. Other times I have used it are for pinging distances from a high seat. In Scotland I use it a lot more.
BTW, in the field we saw 4 roe, 5 muntjac, a fox and a barn owl. Sadly the only ones close enough to offer a theoretical shot were the last two. We didn't shoot the fox (at 10 metres, and it never saw us) as there was a nice, clean, 6 point buck in the field at the same time.
That's stalking.....
