I'm with Brendan. I've been using a Tectron Sight Tube, Cheshire and Autocollimator for about 20 years. Great gear. The book that comes with the Tectron set (Perspectives, by Vic Menard) is worth the price of admission alone. It's a no nonsense guide on how to collimate a newt and is really worth a read.
I would be keen to get the Catseye colimation tools one day as they look quite nice, but really, the Tectron tools do the job admirably.
