Let me tell you this:
I have gone through every possibility for swapping my car and Dave is still the cheapest option (and will do the highest quality work with over 50 MR2 swaps under his belt).
I will have had 2 swaps done by him at the end of this month. I wouldnt steer you in the wrong direction... it took me months to figure out that Dave is the best/cheapest option.
My Gen2 swap (the first time) put me back about 5800 clams... but i had other things done not totally necessary for the swap.
I reccomend Dave 100%! Great guy, straight foreward, cheap, and great work. I cannot say enough good things about him.
