If I waas in the US I would be looking at the dana300.
Nearly as strong as the atlas, but not as expensive.
Heaps stronger than the np231, but more expensive.
It is sort of the middle ground between the two.
One advantage you get is the twinsticks
The costs do add up though, and it would be better if you could fabricate your own flip kit for it as the stock dana 300 has the driveshaft outputs on the wrong side for us tj owners.
You have to remember with the atkas and dana300 you don't need to buy an SYE kit anymore so you save US$220 or so there alone.
dana 300 - US$150 second hand
4:1 kit - US$700 or so
flip kit - US$550
You can also upgade the output shafts to 32 spline versions or similar.
If you have the money go the atlas - you will never need another t-case
If you don't quite have the money, but can pay in stages, go the dana300. will end up close to the atlas
If you don't have the money - or are going to stick to 33's, 35's or similar then get the 4:1 terlow.
my .02 worth anyways...
