Very good deal. You can routinely find them in the FS/FT forum for around $ 100, but not too much cheaper with shipping. 19" LCD's go for $150-$200 new and $125- $140 used.
If you don't want it, or want to spend a bit more and get a 19" that may be the way to go. In fact, if it works fine, I'll buy it from you (the 17") if you want to go that route.....Shoot me a pm
