Dont listen to all the d40 bashing from the d22 boys, I quite often go out with a few guys with d22's and I get better economy and drive in offroad situations with more ease than them because of the extra power and the better 1st gear ratios, you shouldnt have too much of an issue of finding a stx in ur price range as a mate of mine is looking into getting one for the same dollar and iv seen a few advertised, goodluck mate and dont hesitate to ask stupid questions coz it might save you some coin in the end

Haha, yeah i'll agree your D40 goes alright mate! In a nutshell, here's my view on the two utes though:
D40:
Pros -
Better on-road
More power
Better gearing
More room in the back
More comfortable inside the cabin
Cons -
Less ground clearance
Electronic 4wd selector
Airbox hard to seal up (can be done though)
Apparently worse fuel economy, but Kyle's ute tends to suggest either on par or better!
Rear LSD is useless (install a locker to solve this)
No option for front locker
D22:
Pros -
Better off-road
More ground clearance
Manual 4wd selector
Free-wheeling hubs
Top notch LSD
Front diff can take an auto locker
Airbox easily sealed (as long as Nissan don't do it!)
Shorter wheelbase
Lighter
Cons -
Less power (easily fixed by a chip/exhaust)
Less room in the back seat
Not as comfortable on-road (a suspension upgrade will help solve this, but ultimately the D40 is a better ride on-road
Less comfortable inside the cabin
