2005 Engine Replacement Knoxville, TN

My 2005 unfortunately threw a rod after 230K miles.
Please share any knowledge and advice you have for replacing the engine. I was thinking of going with a ~150K mile used 2nd engine and finding a local mechanic to do the work.

How much would you be willing to spend on this repair? I'm concerned that I may be too emotionally attached to make a rational decision. I purchased her a year ago for $3000.
