Keep an eye out for an old RS800 kite on ebay.
Suicide blonde had one, this extract is taken from Iain Christie:
'It's an RS800 kite which measures at 21.5sqm. To make it class legal it needed to lose 0.5sqm, however with the way the measurment rules work in practice it was far less than this. Leaving the head and clew as they were, I took a sliver of material out of the kite that was only 10cm deep at it's widest point, halfway up the leech. Almost not worth bothering with!'
