I am new to metal detecting as well, I read most of the factory hype about 6 or 7 detectors and like you I had a tight budget so after reading a lot of pros and cons I settled on a Bounty Hunter Pioneer 505 from Kellyco's scratch and dent detector was brand new and no marks on it just was re-packed in a different box but got it for $199.00 plus a set of head phones for another 36 bucks. It fills my needs to enjoy the hobby from my point of view the (best) detector is the one that will let you have some fun and fits your pocket book. I am sure there are other detectors better suited for certain things. Kind of like 35 mm photography you pick a good camera that fills the bill then choose a film with the ISO to do the best job like 100, 200, 300 etc.
