I've not used an EABCO barrel yet but have had good barrels from Shaw, Criterion, Shilen and PacNor.
I wouldn't hesitate to buy another Shaw.
If you're swapping barrels more frequently, I'd suggest you make a wrench to fit the recoil lug.
You can tighten and loosen the barrel nut with wrenches rather than a barrel vise and a wrench.
Two lug wrenches shown in the right of the picture.
Savage has the recoil lug keyed to the receiver so it's easy to spin a barrel on or off.
Marlin recoil lugs aren't keyed so a wrench on the recoil lug won't help as much and you have to align the recoil lug when tightening..
