Lots of OM "T-mount" (M42) adapters on ebay for dirt nothing. Just make sure it is OM mount and not 4/3 mount. For some reason the eBay crowd keeps callinh the 4/3 mount OM 4/3.
I have 2 of them. One is actually a reversing ring that also has 42mm threads on the ID.
I did a search on ebay and found several for about $12-$15 bucks. I found this one mounted on a Macrotel 150mm f/4.5 Bellows Lens for a steal. If you ever plan on getting a m42 bellow unit this would come in handy.
