Jim's not tearing you down. He is just very matter-of-fact about bike pricing. You asked, and he answered. Please don't be offended. The man does not waste words, and he knows of which he speaks. Before this thread was created, your query likely would have met with "3.50" so don't feel torn down. But if you needed a part that no one has, Jim may well be the one here that would send it to you, unsolicited.
I think his point was that a flea market sales environment will and should expect to bring the lowest offers and prices. That's what flea markets are all about, low labor, low overhead, low price.
He also gave you a fine example of how you can get more for that bike without much effort at all, just like the flea market vendors he deals with.
Then he rationalized the expectations you may have about pricing from the forum. We generally price based on make/model/condition/venue. He's letting you know that your venue will result in a much different price than you may hear, here.
Jim and Bill gave you the market info, and the others have pretty much helped, also:
1-Flea market will bring you $25-$50 max, due to the sales venue.
2-The saddle may be worth as much or more than the bike, if it's a leather Brooks in good shape.
3-It's a nice bike but there were an awful lot of them made and brought across the pond.
4-It's a lower end bike in the Raleigh line, so being made in England doesn't help there.
You're far better off on local Craigslist, or a free trader ad, but it's your time and money. In decent condition, with no more than $30 in parts needed, it's a $50 bike. If you get that offered, I'd take it.
I'm RobbieTunes, welcome to the forum, and we're here to help. We're also great looking, highly intelligent, and friendly as a bunch of hungry cats.
If you really want to get torn down, try the road forum. Whew, those guys are sarcastic.
