Best Fan Jets?

[SPECI4L]

As has been mentioned somewhere in another post (but I'm too lazy to find) Gardiners fan jets aren't quite doing it for me.

With my last couple of brushes (Xtremes) I've found the brushes outlasting the jets with the spray becoming less fan like while there's still life in the brush!

Any recommendations chaps?

Where from, how much, difficulty in fitting etc.

I've got a set of these green ones in one of my brushes. You have to drill out a larger hole and glue them in your brush though.

I think the other post mentioned the green ones being better than the blue... but are either of them worth £8.91 each?

At that increase in price over the Gardiner ones I'd expect them to be awesome!
