This kind of take has always puzzled me. Offer and demand..nobody gets to decide what an acceptable price for a NOS CRT screen is except the buyers. You can of course decide you're not willing to pay that much, though. And if the majority agrees with you the seller will maybe lower the price or hang on to them if he can afford to storage, if anything new-in-box CRT's will go up in value, not down. I wouldn't pay that much for a 17" myself either, mind you. I just don't understand the condescension, I mean it's 200 bucks it's a lot of money but not outrageous and your chances of being able to run it trouble-free for quite some time are substantially higher than any second hand. I've bought 3 CRT's in the past 2 years and in total I paid less than 100 bucks, but I've had issue with two out of the three (fixed one of them and half-fixed the other one, not perfect but usable).
For OP: based on the above I would never say 195 bucks is highway robbery but it still a bit expensive... is your desire to have a CRT (and goddamn I understand that 😁) worth $195? Is 17"your ideal choice? Is NOS really what you want to minimize trouble chance? Are you willing to be patient and wait for a hypothetical better deal, or is the itch worth that much money? In my opinion it only goes down to that in the end.
