Cheap version of sprocket or mini instax please?? Budget £30-40

[Marshmallowpops]

Our budget for SIL is about £30-40. A while ago I saw the Currys offer on a mini instax for £43.99, told DP and he said it would be perfect. She has 4 children and loves taking photos, we thought it would lovely for her to be able to print them off and display around the house, so I ordered it, was super super happy with the perfect present, then they cancelled all the orders as they didn't have the stock!!! Was very disappointed and since then I've had no good ideas, wondered if anyone by any chance knows a cheap version of either an instax mini or a phone photo printer like a sprocket, had a quick look on eBay and I see there are some products, but would love recommendations from anyone who's actually bought and used something like this, as I don't trust fakes! Or alternatively had any good suggestions for SIL? Thanks so much in advanced
