Rug Recommendations?

I'm not sure what my deal is with rugs.  Everyone else seems to be able to find a good deal on a cute rug around here.  I keep striking out.

You may remember my dilemma about finding a rug for our living room. After extensive searching, I finally found the perfect rug on Target's website.

Now I'm having the same issue, just in the master bedroom now.

I'm in love with my comforter and sheet set.  It's grey and yellow and I want to bring in some mint green accents around the room.  This is what you should know about me.  I'm not a matchy-matchy kind of person.  I really want to be able to mix and match patterns seamlessly and make everything look like it was just meant to go together.  I haven't mastered it yet.  So I thought that a rug would be the perfect opportunity to bring in some color and some pattern and make it look like it all went together.  But, since I'm super dependent on other people's opinions (it's a flaw, I know), I need to know what you guys think.

Options!

Let's break these down.

The picture on the left, obviously, is my bedding.

1.  From zulily.com
Pros:  It's yellow houndstooth.  I'm obsessed with houndstooth.
Cons:  It's a 3.5'x5.6' rug.  I'm really hoping for a 5'x7'.  And it's $99.99.

2.  Currently in my Target store.
Pros:  It's gorgeous in person.  I really like the idea of doing a completely different rug pattern and bringing in the different colors.
Cons:  It's $152.99--that's the sale price.  Not really the ideal pricetag I'm looking for.

3.  From Urban Outfitters.
Pros:  I'm obsessed with chevron right now and it's mint green and it's only $89 for a 5'x7'.
Cons:  Is it too different?

4.  Same rug as #3, also from Urban Outfitters, just in yellow.
Pros:  Again, I love chevron.
Cons:  I'm nervous that it's too much yellow.  And I'm afraid that it's going to come in the mail and it's going to be a different color yellow that's on my bedding and it's going to clash.  Ugh.

Opinions?!?!
