No Mark it's the Berea Elegant Sierra.
Neil, the Axminster ES is frankly shite, and even at 50% discount it's still shite. The Berea ES is a kit of quality - the plating, the fittings, the mechanism, the CB - they are poles apart.
Dan, speaking for myself, (and I posted a thread recently asking if there is a UK supplier), the Berea ES in gunmetal and chrome is one of my best sellers - I get through 5 to 10 a week. I see exactly what people are saying about the dilution of your Zeta sales, but, again speaking for myself, the main attraction apart from the quality of the kit, is the versatility of the tube. I glue up large batches of blanks in advance, and I can then take the same blank to make into a whole raft of different kits because the tubes are interchangeable.
It's a tough decision you're going to have to make, but if you can produce a Berea ES equivalent in gm/chrome, using the same tube, for about a fiver, I would certainly buy them at probably 50 or 100 at a time, but I do realise I am but one customer.
