^^^ Dezzy, I understand.
I guess it all depends on how many miles you do in a year, and how long you plan to keep the car for. I'd rack up 35,000 miles in a year, so 105,000 in 3. If I intend to keep the car for 5 years, I'll be back in the danger done again...
I've always done my own wrenching, so perhaps my assumption that it will be cost effective to go 01E is unfair on others...my current outlay is £379, and I have all the parts required. I've just sold one of my 01E trannies for £325. My outlay would have stood at £704, still pretty cheap.
As long as you know where to search for parts, you'll be sitting pretty...
