NIKO, I just built my dad a budget computer and used the first MoBo you had listed there. It posted first try for me, OC's like a champ, and had everything I needed in a budget board. My only 2 knocks against it was it only had 2 slots for memory, (so if you ever wanted 4Gbs RAM, you would have to by 2x2GB sticks, instead of 2 sets of very affordable 2x1GB sticks) and it only had a place to directly plug 1 case fan to the mother board. A simple adapter allowed my other 2 fans to work, but it was a bit of a nuisance.
Long story short, anyone of those boards should be okay.
Oh, and if you are willing to anti-up a bit you can get a Q6600 Quad Core for $200. Be careful though, I haven't tried this CPU in any of these motherboards, so I'm not sure its 100% compatible. It should work, but sometimes things are a little screwy. Also, this is OEM, so no cpu fan is included. If you are with in range of a Micro Center store, you can get one with a fan for the same price.
The CPU Zero recommended is a great one too.
Edit:Sorry, I lied, this is actually the MoBo I used:

Pretty similar though.
