Default Can I rebuild my 87' 924S Motor? What to look for...

I have an 87' 924s that was running splendidly *cue sad music*, but all of sudden started running very roughly. Pulled over as fast as I could and checked the oil level....low. Oh boy. Added some more oil and nursed her home. I'$4-6m contemplating an engine rebuild, but wanted to get some thoughts on:

1) cost to rebuild professionally - I'm seeing $5-10k
2) buy a rebuilt motor - $4k and up
3) rebuild myself - $4k and up?
4) Swap in a used engine - ~$1-2k
5) Do an LS Swap

Now I'm the first to admit I'm relatively speaking a car noob, so please feel free to point me to other links I may have missed.

Now the primary question: if I was to rebuild (myself or otherwise), what would I need to look for to determine if it can be rebuilt?

First thing you want to do is run a compression test as well as a leakdown test, then you drop the oil pan
and have a look at the rod bearings !
Those engines are tough and can take a lot of abuse , not sure a low oil level can do a whole lot of damage, especially if you pulled over quickly ...

Don't panic yet !!!
