It's a boomer 2000 made by Randy Lackender in Iowa. I love it and can't see how I could live without it - it has it's limitations, but I don't do enough trenching to justify the need of owning a mini. Downside is it tears up the yard due to having to spin a little to dump, but they do make one that has the pivot in it. Never have timed it, but I'm guessing I can comfortably dig 100' x3' deep in moderately decent soil in an hour. I use it to transplant trees, uproot trees (big ones too), chase ground hogs out, pick up logs for cutting firewood. If you get one make sure you get the thumb he makes....very handy. Easy to throw on the trailer when you need it.
