Mostly use these for is rear caliper brackets on vw Touareg
It's hard to pass on the VIM unit above. I don't do much work on Euro vehicles but how often do you need a triple square on them? The only time I've ever needed it is when I had to remove a shroud for an oil change on a beetle.
Cheapest and bit sockets generally don't go well together. May as well throw your money in the trash and save yourself a trip to HF if you'd actually consider that place for this particular product. And this isn't just a random HF bash, their hex and torx are often improperly sized which leads to a much bigger headache when it either breaks off or doesn't fit stopping you in your tracks.
VIM are a known quantity (good quality) and about as cheap as you'd want to go.
The VIM set is already so cheap and VIM products are so well spoken of. I think that if you are going to use a triple square on fasteners that are in good shape and you don't plan on using it that often then a junk set will cut it.
The triple square, also known as XZN, is a type of screw drive with 12 equally spaced tips, each with a 90 degree angle. Common sizes are 6, 8, 10, and 12 mm. Its name derives from overlaying three equal squares to form such a pattern with 12 right-angled tips (a 12-pointed star). In other words, 3 Robertson squares superimposed at 30° rotation. The concept is similar to that of the double-square—in both cases, the idea being that it's like a square (Robertson) but can be caught at more frequent angles by the driver bit. These screws can be removed with standard Robertson bits.
Triple square drives are often used in high-torque applications, such as cylinder head bolts and drive train components. The heads are hardened and tempered to withstand the driving torque without destroying the star points.
Triple square fasteners are commonly found on German vehicles such as Audi, BMW, Opel, Mercedes, Porsche, and Volkswagen.[48]
Never heard of tripple square, is this the same as torx?
I prefer short driver bits, they're less likely to twist on you. They only need to be long enough to fully engage the head of the fastener.The VIM Tools discretely state stubby. Not sure if this really makes a difference or not as one can always use an extension to aid.

+1. Cheap triple squares are a REALLY bad idea. These are used in high torque low access applications. Brake parts, half shafts, engine mounts, seat mounts. You often won't get a second chance with one of these.
Thank you all for the recommendations. The one from VIM Tools caught my attention the most after reading through all the comments, but this set is all 3/8" drive.
I noticed the Capri set includes some sizes in each drive, http://www.amazon.com/dp/B007UQLR9U/?tag=atomicindus08-20
Are all three drive sizes necessary?
The 9pc VIM Set XZNS1000, includes bits in 1/4", 3/8" and 1/2" drives.

Not sure on model number but my Cornwell set is all 3/8. I think it goes down to 4 or 5
Let me jump in. I also have the VIM set. Way stronger than they look. I am very pleased with these sockets. A few of them are quite high milage and still fit great.
