[vcf-midatlantic] OT - Advice for CRT monitor price

I am looking at a used Sony PVM-97 8" CRT Black and White Video Monitor on eBay. The seller doesn't have pictures of it powered up, so I can't tell if it has burn-in. He is asking about $90 plus shipping. Can someone tell me if they think this is a reasonable price? He has a small quantity available and only provides one picture. Should I demand to see actual pictures of the unit powered up? Thanks, Chris
