I picked up a Ruger Single Six several months ago, it had a chipped grip panel and no magnum cylinder. Got it for $240 IIRC. Might have been a bit less, but it was a steal in my opinion.
I would say start perusing the pawn shops and gun stores and pick up the first one that you find for a fair price. I always will make an offer and let it marinate for awhile if the price is too much. Spend some time and you can usually get it cheaper, but you could also lose it too. Who cares who made it. If its what you are looking for then its the right gun.
