A budget of "not looking to break the bank" is pretty subjective and gives no real indication of what your budget actually is.
My suggestion would be to skip the weapon mounted NV, especially if you're on a budget. Why? Because if you're shooting at night, then you're moving at night which means you're going to need one on your head as well and means buying two units. Even without the budget I (and most others) prefer a weapon IR laser and NV on a helmet or skull cap.
For $2500-$3000 you can pick up a really nice new PVS-14 with a high quality automated tube and manual gain and a warranty. You can get used units for less but I always prefer buying new, just personal preference. For what most people want for used 14's that you have no idea who built it, what tube is in it, or anything else, you aren't much under what you can get new for.
If you can swing it, dual tubes are the way to go. Starting in the $6500 range you can start getting into some really nice stuff and they go on up above $10K.
Then get yourself a weapon mounted laser, I personally prefer the Dbal-D2 for a commercial unit which can be had in the $900 range, but there are other good units too.
