The price could boggle too !
Oh yes, we'll have to pay for it
But then again look at the price of the Alter 71 with all it's frequencies and deep layers of settings. Technology is getting cheaper and it may be that machines have a lot more in them for a surprising price tag. My Lenovo tab is loaded with features for 90 quid, it would have been 400 7/8 years ago.
The Deus and CTX were a bit "out there on their own" a few years ago wouldn't you agree? and therefore it's plus £1000.00 if you want to be in their clubs, however, more and more tech is available and more and more manufacturers are prepared to offer this at less. I can't see XP lowering the price of the Deus any time soon, they are still selling well and besides, it would be seen as an act of admission that the opposition are onto something, but the next few years could be very interesting.
I do think the days of the tones only machines are numbered though. We all know that Deeptech and some others have their fans and do a great job, but I just can't see them appealing to enough of the market in the coming years, not when you have the temptation of so many detecting computers and gizmos right now and even more-so in the future.
