You have a good point and one I readily concede.
I was always led to believe that you can't really tell the difference between regs past a certain level. On a machine yes, a diver not so much.
Apparently you can.
But as you say the AL is (in the US at least) 3 if not 4 times the price of the Deep 6. Is the AL 3-4 times better. No. It's not even twice as good. If fact it's only marginally "nicer to breath" Obviously outside the US the price difference shrinks and you have the additional shipping cost, but still there is a good chunk of change between them
I really and honestly think Deep 6 has a nice product, certainly one I'd recommend. I'd like to see the grip on the Din fitting improved, as that would be the most annoying for me (based on my normal experience) for others it may be what they're used to and they don't care.
While I nit picked for sure, for me what stands out, is that they've made a reg that is really, really close to a top model, and they should be really proud. Maybe as they develop further over time it will be equal if not better, who knows.
What I did note is that everyone I showed it too, and told them the price was impressed.
I'll certainly be keeping a close eye on them in the future, as it's a brand to watch.
