I agree with "The other Jeff". Building teaches you more than buying. Kind of like locating your own claim versus buying one or just working a club claim. I've built the majority of my equipment over the years and not only was it fun, but I learned what works and what doesn't. Everything from Long Toms to Highbankers has made its way out of my shop. LOL... If I could have made my own pumps I'd most likely have given it a try as well.
We've also found gold in our yard. Now I just have to figure out where to put the swimming pool, koi pond, underground parking as well as where to plant all those big trees!
