I was in the same boat a couple years ago OP, wanting a similar torque range, not Snap-On cost but wanted American-made (or at least no Chinese) and something of good quality.
I ended up with a CDI with a range of 40-250 ft-lbs and a Precision Instruments with a range of 100-600 in-lbs. Between the two, they will handle pretty much anything I'll likely ever need.
I went with split beam types for both. I think I had a couple reasons for that, but the only one I can remember offhand is you don't have to worry about removing any tension when not in use; you can leave it set to anything, there is no tension applied until you use it. The only downside is you can only run these in one direction, but that doesn't really worry me.
