I had a tak tb007 for several years before upgrading to a kubota u15 a year or two ago. Basically twice the machine the little guy was. I've only missed the small tak once, but even then that was only for a days work. In basements with the rops off a one ton mini is worth it's weight in gold. Otherwise I'd stick to the two ton machine. Jmo.
I found the brand I wanted and then started looking at all those dealers close to me, slowly expanding the circle. Couldn't find one on the larger used websites. Also, found my track loader on Craigslist, private owner. Did a national search for that, not local.
Most of the rental places around here have one ton minis in stock for rent. I would think you can find one around you also if you look hard enough.
