Not sure what loads is to you, but I was in your shoes last year and decided to go with a slightly nicer one without breaking the bank, and I LOVE the one I got.

This cost me $90 USD (~73 GBP). I think the price now is reflective of COVID prepper panic, so I'd wait if you can.

For that price you get a non-stacking 6 tray timed- and variable temp dehydrator with a fan. It works great and it's so far very reliable. The stacking tray passive dehydrators take so much longer to dry food and seem to be harder to use in general. Before I had mine, I had borrowed a stacking dehydrator and it took 3 1/2 days to dry a batch of spaghetti. With the one I have, +-12 hours.

A few weeks ago I dried enough food for about 50 backpacking meals in a couple days - and I'm not lacking variety. I have at least 8 different recipes in there.
