Have the Explorer, SE (sold), Etrac, 3030 and seriously thinking of getting the Deus for the simple reason of weight is half of the Minelab. I had/have no problem shelling out the coin for a machine because I know there isn't another hobby out there that will steal my passion away. So if you think there's a passion to dig why not get a good machine to play with if the coin is available. Between the two machines Etrac/3030 I would really have to say the 3030 for hunting heavy iron infested sites. To give one example a small park Etrac was down to finding hardly anything for coinage, in came the 3030 and I must of be up 20 silvers and a couple of hundred coins. Why such a difference one would ask? Well what I was finding was a bottle cap or two with every coin, or a nail. So the way I see it was the Etrac nulled out or the iron was just masking enough where the 3030 picked it up, the numbers didn't mean anything but the sound was the key to digging.
In boating they call it two foot-itist where you see a person always upgrading by a couple of feet, working their way up to the cruiser. Same thing happens in this hobby, buy low, buy again, buy a better mid/upper end machine, then bite the bullet and get the high end one.
I would really recommend a Ace 350/AT Pro (if that's what they're called) in what I've seen over these past few years there's still a lot of great finds being made by these machines, not going to hurt you too bad if you take the batteries out and flea bay it if you find swinging a coil and getting dirty wasn't for you.
