Well in my part of the country (SC Kansas) you just don't often come across anything more than Yugos or Norincos let alone anything thats looks really good. At the show today, which was somewhere around 950 tables, I saw 2 romies and 1 russian! If there were more i would have seen them, as i looked and looked. Theres a Russian at $505 on gunbroker right now but of course its got the box and all, but $505 really does seem high to me.
FWIW a couple of years ago Century had a few Romys for sale @ 180-190 bucks IIRC. There weren't many and they went quick. The one I got was all matching (execpt stock which didn't fit the action properly) and in at least VG+ condition. Based on that and their continued relative rarity I don't think $250 is unreasonable for a nice matching example. I wouldn't pay any more than that though.
I paid $160 for my E++ Romanian, but that was at least five years ago, maybe more. So if the one you're looking at is in similarly superior condition, I'd say that it's a little high but within haggling range. About three years ago I saw one at a gun show for $225, and it wasn't mint by any means.
Of course, as you say, the part of the country you're in can be a factor, too.
IIRC, I paid $165 for mine about five years ago. It had very little finish left, but the bore was excellent & the wood was nice. I passed over a bunch that looked like new, and selected this one. When the clerk told me I could have a much nicer looking one for the same price, I told him to look at the serial number. It was 666. He just smiled & did the paperwork.
They're really price gouging on the Russian's right now and they're not really worth it since there are plenty out there to be had. The max I would go is $300. But people buy them and artificially inflate the price.
