DIY superdrive powerbook replacement

I intended to buy a superdrive for my powerbook G4 as the current drive is not working.I enquired at a shop which sold mac and does repairs on windows machines but they said it was very difficult, and to take it to Apple repair centre.

I have never opened a computer but have read online the pictorial manuals about installing a superdrive.
I am now not confident given the shoop response. ARE THEY BEING DRAMATIC OR COULD i EASLILY DAMAGE OTHER COMPONENTS AND REALLY STUFF UP?.
i AM NOT A HANDS ON PERSON BUT TO SAVE $600 IN MY CASE, i WAS GOING TO GIVE IT A TRY

Powerbook G4 17 inch .....Online Manual states
The optical drive ribbon cable is very fragile. Be sure to gently lift up the cable on the sides. Do not lift up on the cable from the end closest to the display.

Lift the optical drive at the right, front corner, and slide it out of the computer (be careful not to catch the PRAM battery cable)

* 1) With your fingernails, grasp the locking bar on either side slide it a small amount (about 1/16" or 2 mm) towards the battery.


* For this step, you only need to move the connector about 2 mm. Pulling too hard or too far will damage the connector.

Are these the areas you are referring to guys.
If my drive isnt working what is the worst I can do if I am slow and careful .
I am tending to not want to proceed from peoples comments

I don't know where you got the price of $600.

If you're not a techy or hardware inclined and have never done this before you are asking for trouble. The parts and cables inside are delicate and working on any Aluminum PB is a royal PIA.

Here is a link to have a third party do it for you and 1/3rd the price if you live in the USA. If you are outside of that, there must be others that can do it for you as well.

A royal PIA !
OK , that sounds pretty clear. The $600 savings is if I go to the apple repairer here in Japan. The land of cameras and computers.!!!!!
Non apple repairers dont want to touch my 17 inch powerbook , and now I think I know why ie a PIA
Getting a 110v-240v external DVD drive that recognises iDVD is that possible. I didnt want cables with my powerbook but can see I now have to chabge my opinion.
