I'm not sure what BC CCDeep's buddy has but if it is a Nekton 2000 it is anything but cheap.
I repectfully disagree with the statement that "Most BC's use 2" webbing." I pondered this statement and visted my local LDS around the corner that carries, Mares, Dacor, Oceanic, Tusa, and ScubaPro, etc. Some of the BC's had 2" webbing and some 1 1/2" webbing. All were quality BCs.
IDI uses 1 1/2" minimum on the 3 BCs that I own (Nekton, Advantage, Ballistic).
The width of webbing that is used on a BC however is irrelavant. 1" webbing has a strength of 4000 lbs while 2" webbing has a strength of 7000 lbs. I feel confident in saying that you, myself, CCDeep or any diver in the world is putting loads on the nylon that comes anywhere near approaching failure.
And the statement: "The 1" webbing itself is strong enough, but there just isn't much meat there to get stitching through, and the light nylon in the BC body ends up taking a big load in a small area. " is wildy incorrect. The stitching, the webbing and the nylon body will all exceed any demands that you may put on the BC in recreational diving scenarios. The nylon used on BCs is incredibly strong. If you dive long enough, you will get tired of it and want something new long before it wears out. No matter how much diving you do.
(I concede that the thicker the material the more likely the durability. But at some point you have to stop and say: What am I paying for and what are my needs?)
Once again, I admit that I do not know what CCDeeps buddy bought. I only assert that in my experience:
IDI makes a quality BC at an affordable price and is anything but cheap. (Though, I'll admit..my only experience is with the Nekton, Advantage, and Ballistic.)
The nylon and materials will exceed 98% of what most divers need.
IDI BCs are highly adjustable and customizable (but more complex to set up and a bit more of a pain.)
The premise that you get what you pay for is true if you balance it with common sense.
I do all kinds of types of diving and not had any major issues with my IDI equipment. (A few annoyances but no more than other gear.)
My best advice is for you to look at IDI BCs and others and then compare fit, comfort, and features in relation to what you want to pay and the type of diving that you want to do.
(CCDeep, the next time you go on a trip and tip the DiveMaster an IDI BC let me know...I'll make sure I'm on that trip.

)
One thing for sure is cheap...opinions. Take mine for what it's worth and pick the BC that is best for you.
