I'm looking to get one, are quite a few inexpensive ones on Amazon UK, which I take to have genuine reviews. Quite a few seem to be badged clones of each other. I've had a look at a few YouTube reviews.
What features, should I be looking for? I'm hoping at some stage to be able to repair, troubleshoot equipment.
I also looked into variable AC power supplies ( don't know if could call hobby use ) but they seem really expensive.
Thanks.
