Yep, the 350 is a darn good machine. Do you do a lot of relic hunting? I had the 350 and the 250, but I mainly hunt coins and jewelry. The 350 didn't really do anything that the 250 couldn't do, and although there is more iron resolution with the 350, you give up one notch in the silver range. The 250 has seperate notches for dimes and quarters, with 3 notches for iron. The 350 has 4 notches for iron, and a single notch for dime/quarter. I decided to part with one of mine, just because I had too many machines. I decided to sell the 350 simply because I could get more for it than the 250. I did find lots of good stuff with it before parting with it though. Another positive is that between what I bought it for new, and what I sold it for, I only lost about $30 for a year's worth of use.
HH!
