Depends on which chemist you buy them from
Depends on which you buy i suppose anything from £50 -£1500 i paid £130 is for my intous 4 but if you go for a wacom dont bother with the Bluetooth its very flaky and wacom are one of the worst for customer support out there, theve know about the driver issue with BT for years and done nothing about it! It a shame because the product is excellent other than that.
