Thanks for the insights, everyone. I ended up missing that auction after all, though I'll keep an eye out for future listings. I've always liked the Pentax DSM. Its a true spotmeter and doesn't require the acrobatics inherent to properly using in-camera CW meters.
One can never be too careful nowadays, especially when living in New York city - we have a dedicated legion of trigger happy 'law enforcement officers', tweaked out on their own egos and only too happy to 'mistake' a benign situation for mortal danger; walking around pointing something that looks like a gun and is held/used in a similar fashion clearly fits that bill. I'm done with heroics, opting rather for the 'ounce of prevention' bit.
Forgive my lack of bravado.
