thanks to all,
I guess the reliability issue doesn't scare me too much being that I just bought a HSE-7. will be in on 7/10. the salesman took me on their off road course in back of the dealership- WOW!!! though 1 1/2 feet of water, on a 35% side incline, on just 2 (one front/one back wheel), up a 45 ft hill (25% incline) foward and backward without using the breaks- NO problem- like driving to the mailbox.
