I got a Cath Kidston one from their outlet store- it wasn’t anything fancy, just a standard change bag with a separate change mat. I mainly got it because I loved the pattern which has little cowboys on it.
It was only €30, so I’m happy with it. I wouldn’t spend mega bucks on a change bag to be honest- I’ve had a couple of bottles leak etc so I just fired it into the washing machine. I’d have been gutted if I’d spent upwards of £60 on one!
