experience is fun... but also a lot of work, a lot money, a lot of getting tools, etc. While it might be great doing it your self and having it work and knowing you built it... you also have the chance you did something wrong and boom...
I think I priced things out and its around $3,0500 for my expected build (that's just in parts) also have had to get about $150 in tools thus far, that does include the minor work on the top end (decking, valve seals and valve job) I have sunk easily 100+ hours into it already... I will take pride knowing I built the whole thing from every single bolt, bearing, part, etc on the motor... assuming it works :-)
But every one has there own priorities.
