Cheapest VU+ Duo

Hi all, I am looking for a new reciever, i would like to be able to record one channel while watching another, must have 7 day EPG, USB port, Record option, and i am also wanting to share my sly uk card with a few friends, i was told about the VU+ Duo and i had a look and was impressed. I just have a few small questions that i need answered before i spend the money on one.

1) Are the clones any good. Are they Safe and are they reliable as a server?

2) Where can i get an Official VU+ Duo at the best price?

3) Is there any other recievers capable of doing what i need at a lower cost?

Any help much appreciated.

Ok thanks. But is there any cheaper model that can do the same....Are the clones a good idea or not?

Thanks mrgmx. I am working on setting up a pc server now but it's proving a lot more difficult than i expected. I have been using windows all my life and linux ubuntu seems foreign to me.
