not all sub 2000, varied from as low as $1650 up to 2500. They averaged to about $2100. I got the job done for just under 2100. I did make them work hard for the price...as I usually do on most things I purchase.
I found Holden dealers to be the cheapest, and independent workshops higher. Put this down to holden having done this job alot and getting it down to a pretty streamlined job. Quotes wernt itemisd, but enquired that chains/guides/tensioner and cam gears were all replaces. Most said yes, only thing some were unsure on were cam gears.
edit.
I did get some up around the 3500 - 4k mark but didnt consider them as I got the feeling they were plucking numbers out of thin air and didnt want the job anyway....as I found some flatout refused to do it.
