I have owned both the OM2 and OM2n. Of the two I prefer the original model because of its awesome low-light metering capabilities. Read more about this here:

If you don't need more than 3.5 minutes of low-light metering, then the 2n would probably be the better choice, mostly because it's newer.
Best,

Slight clarification here. The 2N WILL do 3.5 minute exposures (at any asa). It's the plain OM-2 at asa 12 that will do time exposures up to 19 MINUTES. The higher the asa setting, the shorter the low light exposure (plain OM-2) John, www.zuiko.com
