I'm a huge fan of the Adam Audio A7's for near field work in smaller to medium rooms.  I think the models are now A7X, with some improvements.  You can pair them up with an Adam Sub-8 or Sub-10 and really never need another monitoring system ever.
 
With that said, I bought my brother some cheaper Yamaha HS5's and listened to some HS8's while I was at it.  I'm pleasantly surprised by those if you want to spend a little less cash.  
 
I just don't recommend dipping below 5 inch woofers, and I really wouldn't tell you to go lower than 7 or 8 inches without a subwoofer, and I'd tell you to have a subwoofer regardless!

If you don't mind getting used units, you can get a lot more bang for your buck. An extreme example is the pair of M-audio BX-8s I got from a guy on craiglist, mint, with floor stands. The guy had tried using them for live performance, and I think he realized his mistake. $100 cash. It was my lucky day.

Checkout the Yamaha HS7s.
My friend/client Fred Coury has both a commercial and home studio.
He got a pair of HS7s for his home studio (thinking they'd just be a modern substitute for NS10s)... and wound up liking them better than the $20,000 monitors in his commercial studio.
If you watch The Night Shift, you've heard mixes done on the HS7s.

JBL LSR305's here. Love em'. If I had a larger space I would opt for the LSR308's. If a tornado comes and takes my house I won't cry if they get destroyed. At that price just go buy another pair.

 
 
ah.....
 
the tornado effect.
 
 
 
 

 

I think there's a lot of great advice here.  Before spending much - what are you expecting in terms of quality? Here's where I am coming from:
 
I started with a passive set of Tannoy Reveals and an Alesis RA 100 reference amp (1000 US total).  It worked for me for 12 years.  10 x 10 foot room - NOT TREATED.  I sucked at mix until I used a reference CD throughout mixdow - my choice was Michael Jacksons #1's.  I eventually added a KRK10Sub 4 years ago because bass had always been my biggest issue.  I thought that might help - but not much.  I eventually studied and found out why.   15 years and still referenced that CD.  I went to LSR2438's - improved, but I still used that reference CD..  Treatment was brought up - that really helped.  It can be expensive - but you can build traps and diffusers and bring the price down substantially. I still used that reference CD.  I just went through and reset up the area, following a few positioning rules - and that helped a bit.  I also analyzed the room with free spectrum and waveform tools I found on the net. I setup the output to be no greater than 85db and that helped even more.  I tested it all with that CD... I do have a nice area now.. Listening to that CD...  
 
The reason for all of that - I was chasing 'quality' and my simple position is this.  Use your ears.  I would take a CD you like to reference and judge your work against, to a music equipment store. They all have a set of test speakers to listen to. Sit or stand in the same position relative to the speakers - about 3 to 4 feet away, with the tweeters at ear level.  listen at a modest to low level.  Listen to a top of the line pair then AB to what you can afford.   KNOW that they will not sound the same in your workroom environment.  From day one you have them home,  use that reference CD..  You will keep the price low and the quality up until you think you can do better by throwing more money at it..
 
FWIW - I get very close to the same results if I use the old speaker setup or the new one. Using that MJ reference CD. The best 10 dollar 'speaker' investment I ever made.   :o)
