there is a "monitor guide" stickied at the top of the peripherals section you may want to read. it has some more tidbits of info such as types of monitors, etc. not really going to help pick a specific monitor but a good read. it also highlights the difference between 8bit and 6bit+frc (also called 6bit+2)
okay, the trouble with any true 8bit panels are that they are rather expensive and generally outside your budget. however, if you can find a refurbished model, clearance model or find one on a really good sale you might be able to manage. might being the key word as europe prices may be higher, availability lower and access to deals not as frequent. you might just need to settle on the 6+2 below but i'd at least take a quick look to see if you see any for a lower price.
for example the dell 2413
http://www.tftcentral.co.uk/reviews/dell_u2413.htm typically has a very high pricetag of $480+ but is a true 8bit panel (actually its 8bit+frc making it similar to 10bit) but if you look around you can find it for lower prices though i'm not sure if even good sales will drop it to quite what your preferred budget is but more manageable than its retail price for sure.. on ebay.co.uk for example refurb models are 199gbp. it might be worth looking around t other 8bit monitors to see if you scan score similar deals. if you dont want to waste time doing that and want 100% brand new from a big dealer, you're going to need to stick to below.
if true 8bit isnt possible, the 6bit+frc panels are not that bad and you would be more than happy with those since the kind of work you'll be doing on the pc doesnt seem like you really need to worry about it being perfect. they are also within your budget.
the site
http://www.tftcentral.co.uk is very handy (especially their in depth reviews). for pricing i was looking at amazon.co.uk
a few models which lookd like they had promise. they might not be 1080p so you may need to do some more searching, but all are 6bit+frc and rated as flicker free.

i'd also look at products from lg, viewsonic, acer, asus and samsung as well as some other dell models. i'd read some reviews on tftcentral to see what they say about the specs.
