At what point to go Dana 60 ??????

I need to upgrade my 8.25 in my Duster. I've been looking at the S60 from Strange. The price is not bad for a complete package narrowed to my specs. I would entertain something less expensive that would hold up like an 8.8 but by the time you finish with everything needed, housing, new axles, narrowing, gears, etc. it seems the cost works out to be pretty close.
