I've recently come into a large number of Sony PVM monitors. These PVM monitors do S-Video (real S-video connector) and Composite and have two sets of inputs (you can do two S-video, two composite, or one of each). One thing to note is that the composite input is a BNC style connector, so you'll need an adapter (BNC male to RCA female) . These connectors are .50 or less and can be found easily online.

The quality is equal to or exceeds the 1702 and 1084's I've been using, it has to be seen to be believed!. I've replaced all my old monitors with these new PVMs, so I've decided to sell off my spares. Here's what I have available. All are working and in great physical shape except where noted:

2x Commodore 1702 - Bottom panel door is attached
1x Sony PVM-14L1 - Build dates Dec 2004
6x Sony PVM-14N1U - Build dates May 1997
1x BMC BM-AU9191U - Input jacks kind of loose but working
1x Magnavox CM8562-074G - Panel door broken off but included.

Prices (does not include shipping)
PVM - $35
1702 - $50
BMC - $20
Magnavox - $20

I'm located in SE Michigan (48134) for shipping purposes. The non-PVM monitors weigh about 27 pounds when packed up while the PVM's weigh 36 pounds packed up (they're a bit beefier). I'm putting these in some heavy duty moving boxes so they'll hold up better in transit.

Here are some pics of my 2600 doing S-Video and the Intellivision doing composite on the PVMs. As usual, my camera cannot do these monitors justice, they look even better in person.
