Hmm... we use dual Dell 2407s and 2408s at work. Can't say I've noticed the bezels being any thinner on the new 2408s. 2408WFP has a few fancy things like display port - can't say I'm bothered. Also, if you've got £600 for 2x24", i.e. £300 each, then I'm not sure the 2408 is in your range - they're over £400 each I believe
Dell S2409 is still <£200 inc VAT and shipping, but is 1920x1080 rather than 1920x1200. Or that Samsung 245 is still very popular and well recommended by many.

Pricing sweet spot for monitors seems to be around the 22" size, so would you consider dual 16x10 resolution? Also, if you care about accurate colours for high-end photo/design work, then these cheap 24" monitors aren't the thing to get.
