Here are my thoughts on it costs to much..
I think its worth every penny... Dreamed about one since 95,, bought one in 01-- Saved me on many occasions of course you must combine it with judgement.
Also I think alot of people are missing or dont realize that the V1 has been priced at $399 for as long as I can remember... so actually the unit is about 35% cheaper than it was in the 90's (accounting for inflation).... and it only gets better.
You either buy a $100 detector or the V1 ,,,, why would you spend 250+ on 8500 etc,,, when you factor in the cost of ownership, resale, upgrades,,, the V1 is a much better value despite higher initial cost.
