Stylus gauge recommendations ?

Any of several of the available digital stylus force gauges should be fine.  I use an Ortofon DS3, because it has a readout to three decimal points, but you can spend a lot less for a perfectly good one.  Don't overthink it, is my advice.

Thanks lewm.

The Ortofon seems like a safe bet as they've been at it as long or longer than anyone.

When I ordered a new cartridge from Gene Rubin Audio (a Hana ML), Gene also sold me a very simple, very modestly priced Ortofon stylus force gauge. It operates like a simple lever. It worked just fine.

Try this works great

Use any of them but don't think a $20 gauge is repeatedly accurate to three decimal points. Good news is one decimal point plus your ears should be fine. ( same can be said for spirit levels - ever priced a calibrated Starret :) )
