I've had my d350 for about 18 months. It is very good and is no slouch in terms of volume and is so light and porrable. Ive used it for most gigs, the other choice being my d800. The build quality is top notch, better than any other ive seen. I got mine by chance from America, I paid 780 uk pounds including all taxes. I'm aware that's expensive, but it is very good.
I have ordered wd800, its now 1300 uk pounds, I think it was previously 1100 uk pounds before the covid sales ban, so that's not an unreasonable price rise.
