All up it cost me maybe $50 AUD not including the IR torch. I don't include the IR torch because the prices vary so much and people have different thoughts as to what is best.
I got the T20 with battery, charger and rats tail and it cost around the $50AUD mark. So I guess all up including the torch would be about $100 AUD ($70US).
I was lucky and got my camera for $7AUD - but they have gone up to $11AUD now, I'll post all the links for the gear I used for you guys. A lot of people use the silicone pipe for car cooling systems, I just used PVC because I had some laying around, but the Silicone stuff fits scopes tighter so there's less room for it to move around. Anyway - that's also personal Preference.
Just for the main bits, it actually cost me $48AUD ($33US).

The prices on a few of the items have gone up since I purchased them, but you're gonna get that. Hopefully the prices are easily enough converted for you guys. You need to get the replacement lens too. The one that comes with the camera is too small and the picture is no good. The 16mm lens gives you a really good picture and is right in the middle of the F rating that sees the IR light properly. You generally want something between F1.4 and F1.8, so I chose F1.6 and it works a treat.
If you shoot powder burners too, I'd suggest probably getting a T67 IR torch. It'll give you better distance.
Here's the link to the torch I got.
TORCH (PACKAGE#3 IS WHAT I GOT)

It's really made me enjoy my hunting a whole lot more. No more spooking bunnies with spot lights, and also no more trying to spotlight and then shoot at the same time (man that's difficult!).
Let me know how you go, and feel free to ask any questions. I'm more than willing to help out where I can.
Luke.
