I have come to the realization that buying the cheapo TDk tapes is really a crappy thing to do for my camera, so I am going to buy some MQ tapes. I have a shoot coming up this weekend that I would like to roll MQ tape at. My question is (and I know this is a dead/overly asked question, I found related threads on it, but somehow couldn't find the answer I was looking for) if I run a cleaning tape through my camera, and then use the MQ's, do you think I will be ok? I plan on getting the camera professionally cleaned, but for now do you think I could get away with it? Is it possible that the TDK's have done irreversible/irreplacable damage to my camera? And what is the going cost (approx) on getting the cam heads professionally cleaned?
