Recommendations for a reliable wheeled backpack for train travel and a book festival, please

[HundredAcreOwl]

Not quite style and beauty, but I'm hoping someone can recommend a backpack with wheels, so it can pulled along if necessary. I'm that bit older, occasionally need a stick, can carry more balanced on my back than over a shoulder.

It is specifically for 'Bloody Scotland' crime writing festival in September, longish train journey, so I need space for a few days clothes, toiletries, chargers etc., a couple of books, and doubtless more books on the way back...iykyk...also water and probably other stuff.

I have looked online, but would really appreciate experience of what is reliable.

UK, so airline restrictions don't apply.

Thanks.

I got one from primark. Think it was about £15/20 and has lasted.

However a lot of shops aren’t selling this stuff anymore as it’s seasonal and they have moved into Christmas autumn.

Thank you, I hadn't thought of looking not on-line. Good to know a well-priced one can last. I dread it breaking down mid-journey from or to Scotland!
