Beyond Economical Repair?

Hello I have a simple manual trolly which has lost it's wheel (I've been told it's becuase I push the Trolly instead of pulling it).

I've tried googling for Trolley Repairs but all I get is Repairers for the posh Electric Trolleys.

Is this trying to tell me to send the Trolley to it's final resting place and get a new one or does anyone know of someone who can repair them reasonably? Guess if I can find someone who does spares I could probably repair it myself.

You can get cheap ones from Argos for around £20.00 but don't know how good they are but if it is going to cost that to fix my current one maybe that's the way to go?

My Dunlop one cost me about £15 quid and has done 5 seasons so far...

Thanks Steve R. and Steve H. for your comments.

Seems to make sense to just buy a new one from what you have both said so that's the route I'll take.
