I, just like you, buy nothing but Sony FD Trinitron monitors. Then I got a flatscreen
There are a few things I would try.
1) Office Depot has the discontinued KDS FD Trinitron monitors, the AV-195TF or something for $174.88, if you can find one. I'm not at work right now so I can't see what stores still had them, but my store had a few until I started telling people, then they sold like hotcakes. (The 17" was only $115). Who cares if it's discontinued, the KDSs still have an excellent 3-yr warranty. If you opt for the extended warranty, they'll just cut you a check if the monitor breaks...no questions asked.
2) Try maybe a CTX FD Trinitron monitor. They also have an excellent 3-yr warranty, which I unfortunately had to use on a 17". After sending the 17" in b/c it wouldn't cut on, they sent me a 19" as a replacement!
3) Wait for Dell to have 20% off and get one of their monitors
4) There's always e Bay.
