I somehow lost a drip tip earlier today and the nearby shops are asking for £10-£15 each - a ludicrous price considering the rda to which it belonged cost £10 itself! What sites are good for purchasing cheap 810 drip tips? Ideally with the ability to select a colour (Purple..); I like resin drip tips and don't like metal nor the look of that yellow plastic material the wasp top cap is made from (delrin I think its called?) but I haven't tried every material available!
