You could check out Robbing the Grave if you like. That along with No Guts, No Glory are my best shorts, I'd say (I see you've read the latter). If you're up for some shameless, unadulterated gore and copious sleaze, you could check out either of the Buckets of Blood scripts.

I can't say I'd recommend the others. Most of them are just larks with a handful written for contests or assignments. Even the OWC ones vary in quality. But if anything strikes your fancy, by all means, check it out... unless it was written before 2007 in which case, it's almost guaranteed to be a waste of your time.
