LX90 Power Cord - Confused

I am ordering an LX90 and want to get the power cord that goes from the scope to a regular household 110V outlet. I called Meade cust. serv, and the rep. said "I think" you want the #541. However, the #541 on different dealer sites says its for the DS/ETX and sometimes the LXD series. There is also a #607 - some sites say it is for plugging into the cigarette lighter outlet only and one site says it includes both the household plug AND cigarette lighter plug. If you have an LX90 and the household outlet cord, which one is it? Thanks, Jason
