Check it out, see if you like it. If it's in nice condition, it'll look nice. The only possible, and probably likely, issue is that it needs a DB25 to VGA cable (which you need to make) to connect a 'modern' PC to it. The only other issue is overscan of 240 line games.
In short, it's not PnP and it's got a caveat or two. If you can get a digital multisync presentation monitor you'll be stylin (check local business/university auctions as well as CL).
