Yep, I've had the same experience. I've put at least 2000 hrs into my dozer build in 2015 including drawings, and I'm still not finished. I'm not going to embarrass myself saying what it's cost and I know I've got $1500 still to tip in. Sometimes along the way I wished I never started. To me money can't buy what I've built - but in reality it's worth $0.00 to sell. So if one can buy an excavator or model ready made, just add your own finishing touches and you're ready to dig dirt and save 2000 hrs building. And a commercial ready-made probably has some resale value too if one decides to move on to another model.
