hopefully this will help someone...
It is specific to the i30 GD model
I got a quote from local Hyundai dealer (note that I didn't write st-ealer) of about £80 for the left and right wipers if bought separately, or £45 if bought in a kit.
I priced up the 26" (AR26U) and 13" (AR13U) Bosch Aero blades which are the Bosch recommended parts. The best I could get them for was about £16 on ebay The Bosch catalogue is here :

Denso. They are called
Denso Hybrid Wipers and are sold by EuroCarParts/CarParts4Less and OPIE oils .
Note that the Denso passenger blade is sold as 14", though it is actually about 35cm long, ie. between 13 and 14".
ECP always seem to have a discount code (30% this weekend) so I got both the front wipers for £20 delivered.
The parts you want are

[/list] Denso Hybrid Blade 26 Inch : ECP part code 485778266
Denso Hybrid Blade 14 Inch : ECP part code 485778136
Fitting is a doddle. Lift open the locking tab, slide out old wiper, slide in new wiper and close locking tab.
Also, the best price for the rear wiper I could get was £7 for the Bosch A310H on Ebay, which is a perfect match for the OE part but much much cheaper.
