Hi kj – since youŕe shooting at 25p, I assume you are in the UK? The best pro monitor brands are Marshall and Ikan. There is an Ikan VX7i 7"monitor kit available on eBay UK right now for £1043.66. This is a very capable professional HD monitor with all of the features you asked for. Here is the promo video for this monitor:
If the Ikan is outside of your budget, you may want to try a 7"Lilliput monitor with zebras and peaking from Amazon UK for £194.
Hope this is helpful!
