First off you need to be realistic, because the people selling these things are nuttier than a fruitcake! I've been buying and selling skid loaders for over 20 years and for the past 2 years or so, and for no reason, the prices have went through the roof. That 743 you talk about isn't worth a dime over $7500 and only if it's in really nice shape with good tires and auxiliary hydraulics. That said the 743 is ancient. And while it does have a bigger lift capacity than a 553, THA would be my choice for your "house" chores. There were TWO generations of the 553: The 21 hp version that has the vertical lettering on the side. And the 22 hp version, with the red and white horizontal lettering. The latter one has a much easier-to-service fuel filter because the air filter on it sits horizontal and doesn't obscure the fuel filter. If you look around you should be able to find one that might need paint or tires for $5000 or less. Fixed up it will bring $7500. Nevertheless wherever these people are getting their prices is beyond me, but it will be a cold day in a REALLY hot place before I pay $10,000 for a 753 Bobcat, unless it had some gold under the seat!!!!!!!!!!
