It's a fair price, maybe a little on the high side. You could always message the seller and offer a better price. Not sure if that monitor is the 5153 or 5154 model but cga monitors are quite valuable, at least $200 on their own if working. The 5154's are more sought after. The keyboards can also fetch a good sum on their own. Also 5170's are less common than 5150's or 5160's and are fairly collectible. If you just want the lot just for the keyboard then it is not a really good deal unless you really need one in Italian ISO which I imagine are hard to come by. I've maybe seen one, but of course I am in the US. The worst case though is you buy the lot and sell the PC and monitor separate to get your money back, although the monitors can be fragile to ship and the 5170's are very heavy so it really would be a hassle to sell those.
