Gen. I will work for relatively simple night hunting or home security purposes. Just be prepared to have a good illuminator, it will often need it. My company brokers a lot of NV commercially and we sell a ton of traditional Gen. I scopes down in Texas and the mid-south to dealers who have a lot of hog hunter customers. They love it. And you should see the banks of IR illuminators some of these guys build.
Gen. 2 is where you'll notice the biggest improvement to the naked eye. The difference is Gen. 2 and above scopes add a micro-channel plate inside the image-intensifier tube that further charges the existing light. Instead of existing light being magnified 2,000-3,00 times as it is with Gen. 1 it is now being magnified 20,000+ times. However the difference in price is going to be significant. Even a very basic 2x Gen. 2 scope is going to sell for $1200 or more, around three times the cost of a similar scope in Gen. 1.
Thermals are getting more popular as their prices become at least attainable for many, though I don't think they'll be down to a few hundred dollars in a few years (nice thought though ). I haven't seen the prices really sink much, if any, on them in the past few years, though the offerings are way expanding. Plus thermals don't use tubes, they're all electronic and use a sensor cell that feeds into a processor and spits out the image you see through the eyepiece on a mini-monitor.
I really think digital night vision will take off in the next few years. Like thermal it also doesn't require a tube or have traditional glass-to-glass light transmission, is all electronic, is relatively cheaper to make than many NV units, doesn't fry in daylight, and shows color (which tends to fade to B&W as light dims). It is a technology still in its infancy and mainly used in low-end monoculars right now, but I would expect to see it improve a lot and a lot more digital NV scopes hit the market in the near future and the next couple of years.
