Electrosurgery Units are an excellent choice as an alternative to overpriced and bulky Laser units used for soft tissue surgery.  Many different units are available; however, I recommend the Bonart ART-E1 Electrosurgery unit.  The quality is excellent and the price makes it the ideal unit.  I personally have used it in my own office and I am very satisfied.  It is not necessary to purchase the Bipolar adapter as it only increases the usable power by a few percent.  The would recommend the adapter if you plan to use the unit in areas where the electrode would touch metal.  Metal might cause a slight arcing of the unit.  In my practice, I have never had the need to use the bipolar adapter.
