Hi,..the RS1700 is an auto reverse 1/4 track machine and without modifications will not play the Tape Project tapes. They are almost always a few hundred dollars more than an RS1500 or 1506 either of which will play the Tape Project tapes. If you check, there is a forum called "Reel to Reel Tape Machines" and there's a sticky at the top with compatible machines. If you're totally new to reel to reel, it might be a good idea to read the "Beginners Guide" which is a sticky at the top of the "General" forum.
It's a good idea to be patient and spend a little time reading about machines before you plunk down your hard earned cash. It isn't that tough to get stuck with a boat anchor when you start buying tape machines.
