Just FYI.
I also did the BEV "free move" a couple of months ago. In my case, I had four receivers being fed off of a DP "legacy quad", which was staying behind at the old house. I had already decided I'd do my own multi-receiver set up at the new house (DP twin LNBs, DP34 switch), so I told the installer to hook up a single 6100 as the "one receiver free" install (thereby ensuring he'd aim the dish for 82 and I'd get two LNBs instead of one and a SW21 switch). Install went smoothly and I did do my own multi receiver hookup a few days later.
When I got the first BEV bill after the "free move", BEV had charged me an extra $200 for "extra receiver installation" (I actually have five receivers authorized on my account). I ultimately got it resolved, but not without a couple of calls to BEV to explain the installer didn't do a "multiple receiver" install. Pretty amazed and annoyed that the "default" for billing purposes is the # of receivers, not the actual work done by the installer. I've been told by a CSR the charge has been reversed, but am still waiting for it to show up on a bill.
