Hello Kenny,
Been using the 1000 myself since '97... it's still one of my favorites and one of the best deals in the used detector market.
Unfortunately, new coils for this machine haven't been offered for awhile but they still show up regularly on the auction sites. The stock coil isn't bad, but I consider the 1000 to be an average performer with the stock 8.5" coil...
I've owned 5 coils for this machine and the ones to look for are (my opinion):
4.5" Sniper coil; decent depth, excellent target seperation and pinpointing, very good on trashy sites.
5.5" HotHead "Ferrett" coil; my favorite and stays on the machine now. As deep (or deeper) than stock but better target seperation. Often hits harder on coins and smaller jewelry.
10.5" HotHead; as deep as the 12.5" but more sensitive to smaller targets.
Again, these coils show up in the 'used' market, with the 5.5 being harder to find. I had a 12.5" myself and recently sold it, keeping the other four.
I own about 7 machines now, started with the 1000 PM and intend to hang on to it. You've got a decent machine, good luck with it!
Feel free to e-mail with any specific questions.
