Just wanting to check, i didn;t really think about the powe rrequirments of my new rig, so i need a new PSU.  im only buying a cheapy, just looking for a recommendation for what wattage i should install.  

At the moment im thinking that I Need about 550W.

Specs are :
Athlon 6000+
M2A-VM Motherboard
2Gb RAM
ATi x1950XT
2xSeagate SATA300 in RAID.  

Go with your gut, I think somewhere between 480W and 550W sounds good

Sounds about right.
