2000 durango PCM? No bus

Can anyone tell me if I can get a 2000 durango PCM from anybody other than my local dealer?? ($500) My durango turns over but won't crank,,didn't get any enging codes but it finally flashed "no bus" while trying to wishfully getting it to crank. Based on the information I've read on this site, the PCM seema to be the culprate.

thanks in advance

I replaced my pcm with a dealer one $435.00, can get a high performance Mopar pcm for about $349.00 or so but you will need to run super which is a bad word these days.
