I'm waiting on delivery on a Vanquish 540 in a Pro Pack. I wanted something my brother could use. I probably researched that model for weeks. I considered other brands. I found the Nokta line interesting, and considered a Double Score, but finally decided on the Vanquish. I'm still working my 705, but waiting for some cooler weather. As I've gotten older, hot temperatures bother me more than cold temperatures. I can always put on more clothing if it's cold, but there is only so much I can take off before someone calls the police.
