I don't know, I guess that all depends on how bad you want it, and how bad the previous owner wants to get rid of it. I got this one for $325 and it's virtually new - doesn't have more than 2 hours on it. It has a YS90, came with a new in the box Futaba GY-1 governor, Corbin blades, and Futaba S9452's on the cyclic. It has a 1qt fuel tank and the YS90 burns less than an ounce/hr at 75-80% power, so it can easily fly for a half hour with reserve.
I'm going to remove the carbon torque tube drive and put a belt in it using a Raptor 30 85t gear and Align 700 Nitro belt and tail assy. And put my Pixhawk Mini on it running AC3.5
So the way I look at it, nobody wants flybars anymore. I do and can go on craigslist these days and just about pick out the one I want and get it for little of nothing. I don't fly 'em stock anyway because nobody builds what I want, and they're set up for 3D. So I rebuild it custom for a scale or UAV heli. And have a new helicopter for 1/3 the price, and is way better for what I want than anything I can buy off the shelf.
I'm not actually a big fan of nitro engines. They got a lot power in a compact package. But the fuel is $30/gallon and they're really cranky and hard starting in cooler weather. And they run really hot in hot weather. I'm going to convert this one to a gasser with a Echo SRM-280 weed whipper engine in it. Bought the whole weed whipper on craigslist for $100 just to steal the engine and clutch off it for my helicopter. Custom make a hub with a shaft for the pinion gear and I'll be in business. Then I'll sell the YS90 to one of the airplane guys at the RC club for more than I paid for the weed whipper
