Cheap ~$200 2.0/2.1 setup

Here is the situation:

I am in an apartment ("technically" a condo hah) and happen to like my neighbors so the sub can/will be happily sacrificed for a boost in speaker quality (can always get a sub later). The living room isn't big (~700 sqft apartment) and the arrangement would be somewhat difficult for 5.1.
I currently have a very old and crappy aiwa (sigh...) 2.1 setup. So anything will be an upgrade.
This is just for TV, music, and occasional games. However, music would be my biggest concern.

Budget: ~200 if possible. I would consider a ~100 dollar boost for a good reason, but honestly I just want something to sound "ok". I got my dt770 headphones for when I need great sound.

Currently I am thinking bookshelf speakers are my best option, looking at some Diamond 9.1's which I can get off ebay for ~250. Any suggestions are appreciated, thanks!

Whoops, ya I need a receiver as well. Guess I am going to have to raise my budget to over $300 to include a receiver.

Though that receiver (http://www.accessories4less.com/make...eceiver/1.html) is a good price on sale, I will be paying that price again just in shipping. However, even for ~$140 am I going to find a better deal?

And, can't find any Polk RTi8 for under ~200 a piece. That's out of my budget.

The acoustic research speakers (http://www.mcmelectronics.com/product/58-12545) seem better (at least from reviews) than the Behringer B2030P. After shipping the acoustic research speakers would be ~$50 more. Thinking it might be worth it....

Thanks for the quick replies btw.

EDIT: Nevermind on the Onkyo price. Ground shipping is only $28 so the final price would be $107.50. Seems like a great deal. That leaves still leaves the speaker choice. Anyone got something better to offer or a comment between spending $50 more on the "acoustic research" over the Behringers?
