I am new to amateur radio, got my tech ticket 8/02 and just upgraded to General a few weeks back. I also have the 706MIIG and was in your situation a month ago. I built a Windom antenna found at http://www.packetradio.com/windom.htm
Cheap and simple, the coax was more than the antenna. I dont get low SWR's in all bands but 17m,20m,40m, and 80m all have useable SWR's so I am not complaining:) and signal reports are very good to boot!
I am saving up to buy a LDG AT-11MP automatic antanna tuner and feel this combination will keep me happy for a long time to come.
For 6m I have a Diamond A504HB Yagi at 35' and for 2m,70cm I have a Diamond X510MA. Hope this helps.
