Trust the advice of the guys here. When I faced an expensive repair I looked at what else I could buy that I would enjoy as much as my revitalized Z. When I came up empty I decided to pay and get it fixed. Long story on how I finally got it running but I'm glad that I did.
Also, I would consider going to Bernie if I had to do anything major and I'm not far from you. I had a bad experiences at RDZ Motorsports and ended up having to fix many things myself. The next major service will either be a DIY or towing it to someone that knows what they are doing and how to run a business.
