All of a sudden the idea of one of these popped into my mind. I can remember when the Revel kit came out at virtually the same time as the ZM kit but with a big price differential. I'm sure the Revel kit could be bought for as little as £25 12 months later and its still not expensive at around £45 but then there is a lot of aftermarket it to may it 'decent'. I'm wondering if its actually cheaper to buy a ZM kit? If so, how much should a second hand one cost? Maybe I'll start a thread in the Trade section !!
