Icandy apple2pear pip conversion kit

[Animaltastic]

Hi
Does anyone have any ideas for where I could source the icandy apple2pear converters to turn the single buggy to double (eBay is not yielding much at the mo)? I'm not due baby#2 until May by which time Ds will be 25months so currently weighing up converting or an icandy upgrade to a (preloved) newer model. Thanks all for any words of wisdom :)
