Do you race on your PC or 360?
Fanatec recently took over the patent for Rinoseat GTR and are mass producing it as the CSL Seat. Mine is on a delivery truck on its way here now.
It's priced at only $299 and weighs a mere 10kg. It also has very cheap shipping costs! Current batch is already SOLD OUT, but if you race on PC or 360 it's worth pre-ordering for the next shipment.
