Stroh just bought himself a 24", so if he doesnt look in this thread, pm him.
HD: you really shouldnt go without it. (full hd ofc)
Speakers: shouldnt be a criteria, really. its a "okayish to have" (mine has some, even considered for monitor-inbuild), because the quality is HORRIBLE no matter how much money you spend on the monitor.
maybe useful for spoken stuff (podcasts/ebooks) and sound unrelated games like wc3/sc2, but for fps games and music ---> MEH.
(mine is prolite ple2209hds)
