I'm looking at getting a nice thermal scope. Is the Athlon Cronus 50L-640 thermal a good deal at $3,500. I'm sure the top of the line Pulsar is better but it looks like this Athlon is about as good as the second best Pulsar. The only thing that looks like it isn't quite as good is the field of view for the Athlon is listed at 8.8x6.6. Any opinions?
