Fortunately, there are tons of great trailers on the market right now. My personal experience is that I'd stick with one of the better known/better reputation trailers like Burley, Thule Chariot, Bob, and others. I got a cheap cargo-specific Aosom trailer some years back and hated it. Something about the linkage with the bike wasn't well engineered and it had this really odd hurky-jerkey, lurching feel when pedaling it. Picture towing something with a slinky as the connection. That was almost 5 yrs ago, so maybe that company has improved their design, I don't know. I bought it because it was 1/3 the cost of the others, but I practically never used it.
One often overlooked factor I'd recommend you look into is width. I did a ton of research before buying my child trailer and thought I had settled on a Burley. Then I had the brilliant idea to double check trailer width relative to my doorway width. It wouldn't have fit through my door. And that was with the single child model! If your bike storage area is a garage or something with a particularly wide door, it may be a non-issue, but I had to go back to the drawing board with the search and focus on ones I could actually get through a standard doorway. (I ended up with a Thule Chariot Cougar which has been awesome).
