Trolley jack - recommendation?

I'm just about to order a trolley jack.

I'm mainly intending to use it so that I can rotate the caravan wheel to fit the lock when it (invariably!) falls in the wrong position in its restricted parking area at home.

I may also take it away on trips as, after one experience of using the Alko side lift jack, I don't think it's up to the job.

Does anyone have a recommendation, as there are dozens of them on Amazon? Is it worth paying any more than about £30 - are they really any better when they cost twice or three times as much?
