Thanks everyone for your suggestions.
So looks like I'm down to these two gauges (I think)
This one looks pretty good. Ranked no. 5 best selling on amazon. But it's got a 3.5 rating out of 5. Some problems were valve stem connection leak and batch of bad units.
Now here's the MOROSO one that got whooping 4.5 out of 5! Everyone seem to like it. Ranked no. 3 on the best selling list. So, I maybe leaning toward this one now.
Any more input from anyone? Probably $30-40 range. Thanks.
