If it's in a covered area, just get a standard one. I've had to replace mine one time over 8 years. I'd also buy a cover for it on Amazon - probably about $30-$50 depending on the size. I leave mine outside year-round, buttoned up in the cover.

I just retired last week after 30+ years in IT, the last 20 as CIO. As you already know, there are many paths. If you'd like to knock around ideas, shoot me a message and I'd be happy to give you some of my biased opinions.
