I have a Swaro combo like I mentioned earlier. The ones I have (I've had them about 15 years or so) are not made anymore. When I bought mine they were about $1,000. They were on sale at Cabela's for $800 with free shipping. I also had a card that said if I spent over $ 750 or more I would save an additional $100. So they ended up costing $700. My wife bought them for me for Christmas. They are great and I have had no problems with them. Swaro did recall them once and did some kind of an upgrade. They are 8x and the RF goes out to 1500 to 2000 yds, depending on conditions. I really like them, they do a great job.
I looked at their website and the new ones are almost $4000! I would have a hard time justifying that much money.
