Exchanging physical stuff is supercool. Why are people not stuck with it? (Maybe because it's not cool to pay your new car with 1.5 million carrots.) I would like to have a cool logodesign for my DIY stuff, but I suck at drawing and a good friend of mine, who is a professional designer, wants to have a very specific effectbox for his guitar, but has no soldering skills. So why not "execute" a classic exchange of these things? I would never pay his hourly wage. This is why I bought this DIY kit (You have to order the knobs extra!!!), waited for delivery and stored the kit in my desk. It's like wine: Store it and wait. To be honest: I had less time and enough other $things to do.
