Pick up the BugMe DVD and a few choice manuals and rebuild it yourself in a few weekends. Save some money and drive your car with an amazing sense of accomplishment 
Invest in some dual carbs, counter-weighted crank, lightened flywheel while you're at it and get even more performance without having to do any machining work.
When I first joined volkswebbin a few years ago, I was afraid to change a tire on my own because I didn't know how to torque them properly and my front wheel fell off while driving... Fast forward to today, there are three engine's in my shop in various stages of tear-down or build including a 2 Litre stroker motor with all the bells and whistles.
Before you go out and make any purchase, spend a couple bucks and get the BugMe DVD. Watch it and see if you're not amazed at how simple it is once you watch them take it apart and put it back together. If you still don't have the interest in it, then by all means let someone build it for you. But you might be surprised at how exciting it is once you get over any fears you might have...
