Adding up the prices for the bits (body, nut and spanner) gives £155.18 plus postage for the Myford one without any collets
The Chronos one is £76.55 including postage
I don't have a current Arrand price list but in 2004 their price was £82.77
- VAT = £97.25 plus postage.
I hope you get what you pay for!
I should say thet the Arrand one I ended up with is a very nicely made piece of kit and fits so well on the spindle nose that it can be a bit of a fiddle to get on. The amount I machined off the collet seat to get it accurate was minute - I made two passes wit the boring tool at the same setting, taking off no more than a thou or so.
