Looks pretty good to me - have a peek here
Doesn't look bad for 39.99
That looks quite promising, would be good to compare it with some expensive kit to see how good it is!
If it was proved to be quite accurate i would defiantly buy one at that price
Having worked with quite a few systems and always coming back to the Dunlop ones as the most acurate, I've found the simpler the system the
better.
I can't see a fault in that system except perhaps the quality of the laser. If thats not good then the distance apart of the laser/mirror and
target effect the accuracy. Some systems I've seen have in the past had very poor lasers but modern ones tend to be much better.
If nothing else it allows a quick check and comparison. Seems worth the money.

Looks very good for the money. I use a cheap laser level and piece of steel that sits on the rim of the wheels, then work it out using trig. This looks just as accurate as how i do it, but with no need for drawing lines and using tape measures!! I think i may have to purchase one!
Using it to adjust would be a bit of a pain, as you would have to do the calibration step each time.
Also it would be difficult to measure bump steer, as you would need to recalibrate each time.
2x laser pointers (one clamped to each front wheel, with spirit levels in to make sure they are horizontal) pointing at a distant fence (i.e. 40feet)
with markings on the fence showing the distance apart of the wheels. That works for me. It does required decent vision and works better once it is a
bit dark.

The trouble with that and most two wheel systems is that your rear tires could be pointing in a different direction to the fronts.
5 wheel set ups are the best way to get it right (5th wheel is centring and holding your steering rack central in the first place).
Making a bracket that bolts on the front and rear of your car and has two strings and a measuring tape is about the cheapest!

What's wrong with string box? 
It will give comparable cross axle accuracy to the tradiition Dunlop gauge, probably stightly better than the Gunson Trackrite.
It is however a bit of a fiddle to use especially compared the Trackrite, but it is small and compact and probably more robust than the trackrite.
Would be quite easy to build a locost version for personal use.
I swear by our Trackrite, we've used it to set the tracking on loads of cars and they've all been fine
