Which Digital Level Gauge to buy?


I want to get a twin axis digital level gauge but am put off by the high price of the CartridgeMan unit.
I have found a gauge (DigiPas DWL 1000 XY) for half the money and wondered if anyone has experience with it or other units.

A wee bit cheaper than the CartridgeMan Gauge but very effective and reliable is the Clearaudio Weight Watcher Digital Tracking Force Gauge. I have a owned a few different digital tracking force gauges and the Clearaudio has been my fav to date.
I have the cartridge man digital level gauge. it is very accurate and easy to level in all planes with 0.0 degree level readings attainable. yes, it is expensive, but if you have highly resolving analog front end it can make an audible improvement.
Cough,cough......i think the OP is talking about digital level gauge to aid in critical leveling in setup, not stylus force gauge.

Thanks for the heads up on the non audiophile product.
