I agree that you should buy it. I bought an 8 year old Spectrum XLT for $450 and still think that price is about right.
Once you buy it, write back and ask people in your area what programs they use on it. I didn't find much until I put out a general plea for help. Once I got the right advice about setting all those settings, I began to find the silver!!!!!!!
The XLT is a nice machine, I have a 12" Hot Shot coil on it and found some great relics and coins. $360.00 sounds like a good deal if it is in nice condition! HH, Mike
