Buying a workshop manual for your car is probably the best investment that you can make. A free one would be nice, but lets get real, a workshop manual in reasonable shape has gotta be worth $10 as it will save you more than that on the first stuff up that you don't make as a result of using it.

Like Jempson said, Ebay is a good source for 1200 manuals & there is usually more than one on offer at any one time. I recently bought three of them [two factory & one Gregories] over a two week period for a very reasonable sum. Now all i need is the factory engine book for the 1200 & i will have the set.
