Advice for repair after timing belt skip

[e5rthuj]

The timing belt on my Megane CC 2005 1.9 dCi 120hp skipped and it has the standard cylinder head damage. This means the following items need to be replaced:

• cylinder head
• head gasket kit
• cambelt kit
• auxiliary belt

There are some affordable offerings on eBay. I was wondering if anyone had any other recommendations where to buy the parts from.
Also, are all 1.9 F9Q engines the same in terms of these parts? I saw that there are many horse power variations and they have been installed in many different models and makes of cars.
