Dont get me wrong now i have used endless amouts of free domains in the past when i was still at school etc. But i find that if you have the money and thats if you do, try and buy a domain they are pretty cheap at less then 10$ and make your site look alot more proffesional.
I mean if you had a hosting site for example and the domain was
www.XXXXX.co.cc
i would take a huge step backwards wouldnt you ?.
