I figured it would come out cheaper to rebuild one. I've never rebuilt an engine but, I wouldn't mind learning. If I can find a low mileage engine for less than 2k that would be great.
On a side note I had a running p30 with the 4bt th400 lined-up to buy this summer, before I learned how rare they seemed to be. I could have paid 1500 but I wanted to haggle down to $1100. Lost that deal
