Does anyone know what price region these are in these days? I've had a pair in storage for over ten years and if I'm honest with myself, I'm clinging onto my youth and I'll probably never use them as they were bought for again! I'm toying with either selling them as a pair with a Pioneer mixer, or individually, to put towards an Atmos system. I've had people tell me they're worth £300 - £500 each? They were bought new by my mother in 98 I think. Relatively good, unabused condition and working perfectly, though the lids are a bit rough. Difficult to know the true value so don't want to let them go too cheaply or if they're worth more as a pair or individually. Many thanks.
