I believe IRunGuns and plainSight Solutions, both site sponsors, had some Pulsar stuff. Scout Base Camp or Brandon Optics might be others to check out. For the price point I think the Pulsar is the better way to go, particularly over ATN.
I would agree with Foxer though. I've had Flir PS32 thermal monoculars, which are pretty mediocre. For the same price I bought a really good PVS14. Not to discourage you from thermal, it is really cool tech and I would love a thermal riflescope, but there are other options.
