Need help on night vision optics.

[beetlebomb]

I hunt alone and have pretty much given up crossbow hunting over leaves from too many deer lost to lack of blood trail (and they just don't taste the same if found the next morning).
I've been thinking about buying a night vision monocular that would help me find my deer.
I called a reputable company that sells everything optical and they said I wouldn't be happy unless I spent $2,000 on a FLIR Scout PS -24 Digital Thermal Imager. I would greatly appreciate any opinions.
