£750?
I can pick a 2.0ltr Zetec up with all anciliries for less than £200, and fit it myself with not a lot of hastle.
Everyone and their brother wants the Puma engine because of the ease of fit, truth be told that it's all well and good, up to 170bhp max, after that you're just wasting money and may of gone with the 2.0ltr.
