DTI

Does anyone know a good place to get a dial test indicator or dial guage (finger or plunger types), or have an old one that they would sell on? I need one to tram my Milling machine, as the head is slightly off perpendicular, so the mill isn't cutting straight slots. I have had a look around at shops, but wanted to check all avenues before making a decision.
Thanks,

I would suggest cromwell, or ebay prob get one for around a fiver

i'm using a Haimer 3d Taster atm and it seems a good bit of kit

Thanks for the help
