Andtrew,take a look at the "for sale" area of Audiogon,under cartridges.The 95 dollar digital guage(measuring in the 1/1000's,btw) was ordered by myself,and a few friends.It is very accurate(we compared it to a Winds guage)and NOW Acoustic sounds is selling it for 185 dollars.I highly recommend it,and for 95 bucks,it is very well priced.I predict that this will be "the" guage to have,and will obsolete many others.Good luck!
Best!
