I bought this ACDelco digital torque wrench. Pricey but amazing. For chassis work, just get a $12 harbor freight torque wrench in 1/2" and you should be fine. The only time you'll need a 1/4" drive is if you're doing inch/pounds.

Though about something like this? I can't personally vouch for it, but it gets great reviews and has a very broad range.
Why not something like this? It goes on a normal ratchet between the socket and the wrench. Could probably make it work with the right sized spanner as well.

The issue with these is that accuracy is really bad below about 20% of the maximum torque it can do. So the first one you posted, the 3/8ths drive 10-80 ft. lb. one, is probably not really useful below 16 ft. lbs. The 1/2 inch drive one that goes up to 150 ft. lbs. will be not so useful below 30 ft. lbs. (which is most fasteners under 3/8" diameter SAE or 10mm diameter metric).
I have a complete collection of beam type and click type ones. Actually, I have at least two of every size in the click type, including a "matched set" from Harbor Freight that I paid $30 for the entire set (with coupons for $9.99 each). If you keep them calibrated, they all seem to work well, and honestly, the harbor freight ones seem to stay calibrated as good as (or better than) the $100+ Matco and Snap On units I also own.
Now for the wrinkle, have you looked at the "digital torque adapters" on Amazon? Something like this amzn.com/B004VYURT0
I've got a 1/2" drive one of those (not that exact unit) and a 3/8" drive one. The 1/4" drive one is on my wish list right now. The one I linked is good from ~4 ft. lbs. to ~150 ft. lbs. They also are known to be slighlty less accurate at low torque settings (below 10% of the maximum), but they operate across a wider range than the click type torque wrenches. That 1/2 inch drive unit would cover most of what a less expensive 3/8 and 1/2 click type would cover. It's comparable to one of my high end 3/8" drive units that covers from 15 ft. lbs. to 150 ft. lbs., but without the difficulty to use it below 30 ft. lbs. Click types have hardly any "click" to them at low torque settings, and can be very difficult to use on the low end of their scales.
Pick up one of these. I've compared mine against torque wrenches fresh out of the calibration lab at work, and it's dead on.
I've had bad luck with torque wrenches in the past, so I decided to go a different route. I gave some "Torque Adapters" a try from ACDelco, and I was really pleasantly surprised! They come in 1/2 inch and 3/8th inch flavors. They are quite easy to use as well!
I use this on my miniplane. It is definitely a good idea to torque plugs to spec. I like this one cause it's much more accurate at the low torque settings needed for the headbolts too. Most mechanical torque wrenches are designed for much higher settings and aren't very precise for what we need. https://www.amazon.com/ACDelco-ARM602-4-Digital-Adapter-4-147-6/dp/B004VYURT0/ref=sr_1_7?ie=UTF8&qid=1536246357&sr=8-7&keywords=electric+torque+wrench

Or just use a torque adapter like this.
The difference between pro and cheap is that professional holds their calibration and can be re-calibrated and repaired. Cheap ones lose their calibration quickly and most service shops won't recalibrate them. Given their cost, it's cheaper to toss them and buy new when they lose calibration. You can buy adigital adapter to check calibration or just use the digital adapter with a regular ratchet
