I have the Burris clip on and their thermal scope. Clip on is nice if you only have a budget for one. I recommend a lighted reticle on your scope to make the impact point easier to find.
Both are in the 35 series which have a limited field of view. I would have liked to try the 50 but they were out of stock when I had the itch.
The handheld has other uses such as looking at wheel bearings to see if they are all even colored. At least that's what I told the accountant when I deducted it for business use.
You are correct that 200 yards is a stretch at night. It gets a little hard to see clearly. For the money it's a good unit for me. Would love to try the thermion someday if the budget allows.
