Agreed, if you're only buying one chuck the ER type is the one to go for. Be aware that they are less secure than the Posilock/Autolock type, if you're taking heavy cuts there is a risk of the cutter pulling down in the chuck. There are ball bearing and other low friction 'milling nuts' available for ER32, which are supposed to enable you to get the collet gripping tigher, might be worth considering.

A quick vote for the ER32 system by Vertex, I bought my set from Chronos but I have also seen them at RDG. They are superbly finished and work extremely well. I also have a couple of "un-named" ones that I bought individually from one of the major machine importers, although not quite so well finished they do work equally well. I have used the Vertex ones very extensively over the last two years, they are still unmarked and as accurate as I can measure.
Is that J&L price one of their special offers on Toolmex (if so I need some) or is it their "value" range? I can't find any listed on their "new improved" web page other than at =A317.50 + VAT each. I might need to raid the piggy bank (again) if you have something I can quote to them to get that price.
F*#k the web page it's crap. No this is out the flyer they send out every month. Just dug it out and correction they are £7.70 this flyer.
What they do is put a special prefix before the normal number so a
11-10 mm collet is AIHHV-34545L looking in the book, web site should show this as a HHV-34545L
Be aware that all J&L prices are less VAT and they charge about £4.40 per delivery so it doesn't pay to get just one item unless you are desperate.
These will be their value range but to be honest I've been buying these for ages and had no problems.
I see from another post that Chronos have the set of 18 for £155. these will be better value for a set as the J&L range of 17 will cost just a bit more than this. Loose collects will work out cheaper from J&L.
Thanks for the information I'm sure their value range will be fine. I seem to have an irrational fear about the amount of "spring" required to hold some of the imperial sizes and so plan to get a spare set of the ones I use most for everyday use. I know they are designed for it but the "bang" that I get when releasing a =BC"drill is still unsettling and leaving them tight for any length of time must stress the steel, good as it is. I know it doesn't make sense really but at that price I can afford a little peace of mind.
Dunno, so I clicked on the link and no they are just the 18 piece set.
Chuck is 64 quid extra.
I bought an R8 chuck on it's own from Chester at a Harrogate show. I reckon they charged me about 27 quid for this as a show offer.
Might be worth waiting, two shows coming up. Pickering, N York's 23, 24, 25 of this month or Fri, sat sun to the numerically impaired, and The Midlands one at TEE's place on the Fosse at Lemmington, this was the old Donington one.
Sets are nice but it's surprising what you don't use. You can get away with 4 collets to start with.
7-6 will hold 6mm and 1/4"
10-9 will hold 10mm and 3/8"
13-12 will hold 12mm and 1/2"
16-15 will hold 16mm and 5/8"
A 5-4 and a 3-2 will cover a lot of the newer solid carbide cutter available cheaply from many suppliers.
