I just got panels from Vafam too. Very good (and friendly) service, very good build quality, very good price.
Their attention to detail re: stress relief etc. is exemplary.
My only complaint is that they use gepco wire, I am not sure which gepco they use, and I hope it's not the pre-tinned stuff, which fabricators LOVE because it's FAST - but it's also undisputably more brittle. But whatever they use, I would gladly pay extra for Mogami wire for my panels in the future.
Gepco is fine, I've wired entire studios with the stuff, but I prefer Mogami by a wide margin.
I think a 'choose your own wire' option, or at least a couple of different wire options would make a great thing even better.
So, Vafam only gets a 999 out of 1000. In short: they rock!
