$700 will get you better monitors than you will need in a small bedroom for demos. There's no point having a set of JBL LSR6300's in a bedroom.
You can get a pair of Fostex PM0.4 or PM0.5 speakers in that range I think. They're not bad for the price. A lot of people have KRK Rokits which are ok. I don't actually think they sound that great but they're relatively cheap and will do what you need them to do. I'd go the Fostex over the Rokits though. Jump on ebay, there's plenty of shit in that price range.
Oh and yes, dkfh is just the samples. You will need ez drummer to run it.
