I own both an Otari and Tascam. They are both GREAT machines. The Otari cost a little more to repair (heads). If you are going the tape project route either will work. Actually, any machine 1/4" 1/2 track machine will work as long as it's working properly. Ralph is correct as always with his post.
Russ at New Jersey factory service is a great guy but there are MANY service shops around the country that can help you. IME the key is to listen before you buy and try every button and lay the machine on it's back and try to listen to the flutter in the motor. The Otari motors can get expensive. Listen to all the buttons and make sure they all work and there aren't "pops". This will only cost you less in the end. Last, with the machine on it's back, look at the heads and use your finger nail to see if there is a groove in the head. If there is a deep groove, chances are it has some miles. Not a big deal but just more money to have them refurbished. The leading head guy is http://www.jrfmagnetics.com/
and if money is no concern (highly doubt it) then get one of these: http://www.atrservice.com/products/item_details.php?item_id=36&dept_id=3
Truly amazing!!! but $10k
Good Luck and have fun with it.
