You might consider taking a Takeuchi TB153 or TB180 for a demo. These machines have the ability to load trucks like a fullsize excavator due to the ability to bring the boom right up along side the cab. It is an excellent truck loading machine. This design beats a typical swing boom design all day. You can also offset dig with out the machine getting pulled around like on a swing boom. After spending a full day on one its pretty hard to look at anything else.
