What crate engines is everyone using??

I build my own, so I'm not much help on the crate engine thing. If you have time, and a little know how you could save thousands of dollars doing it yourself. Do some research, buy an engine building book...its really not too hard. You will probably have to buy a few specialty tools, but you will still come out FAR ahead monetarily....and it just feels good to be able to say, yup, I built that motor :D.
