2k sounds quite fair. i think the engines are hard to price, aaz is hard to find in the US, but at the same time the TDI is better and available here, but if you are just looking to upgrade your 1.6na or 1.6td, the aaz is a much easier swap that is still leaps and bounds above a 1.6, with out having to worry about sourcing a pump or anything and it nearly drops straight in, its really stuck between the price of a 1.6td and a tdi, because at some point if the price is high enough you may as well go tdi.
