Hi,
I have 3 brand new standard resolution pentranic 29" monitors. These were the ones on Ebay a while back. They have a composite to rgb convertor installed but that can be easily disconnected if you want to hookup straight to rgb. Alternatively, you could solder to the rgb header on the composite to rgb board if you wanted to keep the composite input.
I bought 4 on ebay and had them shipped from Montreal to Toronto. I'm currently using one with an arcadevga board from Ultimarc. The combination works fine with the only caveat being that the vertical hold range isn't as tolerant as some other monitors I've used. For example, you can't setup 60Hz and 50Hz resolutions without having to adjust the vertical hold. The tolerance is more like 5Hz instead of 10Hz.
There monitors are available for pickup in Brampton.
