Diffuser attachment for hairdryer

[lurcherlove]

Is it possible to buy a diffuser attachment separately? I recently bought a new hair dryer (tressemme 2200) but have started to embrace my curls again and would like to try a diffuser. But it feels wasteful to buy a whole new hairdryer. I'm struggling to find just the attachment though, except for dodgy looking ones on Amazon.

I bought one from Amazon. Was fab.

I bought and use this one - it's a great size and works brilliantly to curl my hair!

I bought a universal diffuser from Amazon too, which has been fine. I have shortish, very fine hair and it suits me to dry it on a low heat setting.
Criticisms of the diffuser seem to be from people who have used it on a high setting.
