Can anyone recommend the smallest? SPG (not the one that goes just in the pony bottle) is there a 1.5" one? I like to string it over my shoulder so smaller is nicer for me...
 
The "thin SPG" sold by dgx and most other on-line ships has a 1.5" face. The housing is nominally 1.75" diameter. They're about the same size as the old U.S. Divers gauges, but thinner. Next step smaller would be to use one of the pony-style gauges with a hose and elbow, which would give you about a 1" face.
