I need to get both my turntables setup properly - don't have a gauge, they appear to be expensive - any reason why I couldn't use one of these? http://cgi.ebay.co.uk/Precise-Digita...d=p3286.c0.m14

Or, any other suggestions (I vaguely rememeber Marco mentioning a digital food scale from a Pound shop - but this looks like it would be smaller and easier to use?)
