I have the harbour freight trailer which seems identical to what the OP posted, I think I got mine for around $230 USD thanks to a sale or a discount coupon or whatever -- you can sign up to harbor freight newsletters and have the discount codes and sales emailed to you.
It is a cheap trailer though. In retrospect I probably should have just bought a good trailer to begin with. There are a few places in Cambridge that offer good deals... like this aluminum trailer with ramps for $1249 (provided you don't need the folding option):

Personally, I don't even find the folding option all that useful on the HBF trailers... once you have plywood on there and a wheel chock or two, it becomes an incredible PITA to actually fold it up due to how much disassembly and reassembly you have to do. If you can manage the space to have a trailer not folded, do it... you'll likely use it much more often. I built a side yard fence to house my trailer so I don't need to bother folding it.
Finally, Paulo you are a dick. This is a forum for anyone to contribute, useful or not, experienced or not. Are you trying to be a forum cop now? A wanna-be moderator? Just lay off already.
Had the Harbour Front trailer for a few years, towed my 700lbs Yamaha cruiser to South Dakota and to Florida with it. All in all about 11,000km, and never had a problem with it. Purchased it from HF in Buffalo and assembled it at home, followed a really good "How to" thread here on GTAM. But be aware, the total cost to build it is closer to $700 when everything is factored in (the kit itself, US exchange rate, NY state taxes, Canadian customs - cannot really avoid that, plywood, paint, eyebolts and other mounting hardware, wheel choke, spare wheel and carrier, reflective tape, ramp, tie downs, registration). On top of that are the costs associated with the car - the hitch, receiver, ball, wiring, plus the installation if not done at home. Not all those costs are for the trailer, granted, but you should be aware of them.
Building the trailer was fun (just think LEGO), but it required an entire day. Working on a warm day made it more pleasant. Also, there is a lot of running around: Home Depot, Princess Auto, MTO, etc.
The big advantage of this trailer is that can sit folded in a garage. And it was light -important as I was towing with a Mazda Protege5 and the trailer does not have its own brakes. Low cost for a brand new trailer is another pro.
Cons, there were a few: as mentioned earlier, very cumbersome to assemble-disassemble, about an hour each due to four very PITA and inaccessible screws. With the wheel choke on, the trailer cannot be folded properly, so on some years I was taking that off as well. Paint was so and so, did not age well, on my way back from Florida got into some snow / salt and that contributed to some corrosion. The coupler was very cumbersome and difficult to operate (compared to my current trailer). The trailer is rated for max speed of 88km/h, wont say that never went faster, just wasn't very comfortable exceeding 100-110 kmh.
In the end I sold the trailer for $400, as I needed one that could carry two bikes. Ended up buying an aluminum trailer for $2,000+, it is a Rolls-Royce compared to the previous, but cannot store it in my garage.
