1995/1996 XLT RMK rebuild

alright so heres the deal
bought a 1996 xlt rmk a few years ago, rode the snot out of it, got a free parts sledd xlt sks 1995, running, blew a chaincase in the 96, switched suspention parts over to 95, got it running, blew that motor (maybe 3000 miles), it was still running but like crap, finally figured out the crank spun, swaped in 96 motor with 11-12000 miles on it, i think the base seal went on that one, or maybe my waterpump of something, started making a bad noise and qui on me, stupid me i got it cooled down and ran it for another mile or 2 down a hill across a lake then maybe 500 feet up a steep climb... seized the engine, it appears that something broke between the pto web and the pto, or maybe it was loose in the connecting rod pin, cant remember tore them down a few weeks ago b4 my clutch jammed up on my 01 rmk 800, anyways

i need to decide between
$150cad crank from a snowest form user in my area, apparntly his boss swapped it out as a preventative measure years ago and its been sitting around as a spare, all good to go so he says

$300usd for a rebuilt crank from jjmachineryonline, then a look on his website and it says + $100 dollars for one with all new connecting rods, and of course he wants my core

or i try and take one of the 3 cores i have (i got a third bottom end for free from someone who said it was good to go but it was all rusty inside, oilseal springs were even rusted thru and laying in the bottom) and buy new bearings and try to rebuild it and balance it myself, or maybe with the help of a guy around here who does car and truck engines, but used to work in a bike/snowmobile shop and says he's willing to give it a try

both the jugs i have look good (monoblocks) i would hone them out, probably use the one from the engine that went out of sync as it didnt overheat or seize, i dont think i would need to bore it i can still see the marks from the machining (the crossthaching or whatever its called)

i cant decide if i should buy new pistons or just do rings, they dont too worn but i guess i should measure and inspect them carefully for cracked skirt and stuff

what do you guys think?

the sled is pretty bagged, but i think with all the spare parts i have lying around for this thing it would be worth having a running motor and maybe it would still be worth a thousand bucks or something when im done prettying it up, or just a fun backup/spring sled, maybe pipe it one day

please bring on the comments and advice

Sounds like so much a ton to me. If you put all that time and work into a job or two you could up date to a newer sled. Plus selling off any parts for cash gets you closer yet.
