Okay, you made me go and look. I have an OM3 and an OM5 (not i5) - both are excellent workhorse mikes but, as Diogenes has observed, are no longer as good a deal as they once were.
Still, if I were looking for an SM57 alternative I'd consider them - not a huge savings but a bit of one and darn good mikes.
Don’t you start in with 57’s on a gooseneck Tim, it was photo’s of those, me, and a very adventurous young lady, that my ex-wife found on my computer, and led to my consequent divorce.
