ebay mate - there is a shop that sells them for all different cars. Can have driller, grooved or drilled and grooved for the same price, all with Mintex pads. The quality isn't fantastic, but they aren't bad for the price.
The wipers are ok, but the fitment isn't fantastic. The retaining clips keep coming loose, and so far I haven't noticed any improvement in the overall performance over a decent pair of standard wipers. Look better than standard though, which is all that matters
Wiper switch didn't work. Apparently the wiring loom is different on the MP3 models which means that the speed asjuster doesnt work. Switch is currently on ebay
