I found RcMushroom to have rod, sleeve, and piston for $130 vs a new engine for approximately $300. This looks easy to answer based on numbers, but it looks almost too easy.
I perfer to buy new one (as your situation). Even you get new P/S/C, the crankshaft is still an used part and I believe the crankpin also worn out too since your sleeve has to be replaced.
$300 could go to a new Plus-12.
