Definitely go with CodingHorror on this

I only mentioned the 512 plan because I remember reading that it was ‘possible’ here on this forum. If Jeff states that it isn’t supported though, I’d imagine that while it works, it’s a terrible experience (using 512). So definitely follow his advice and go the 1GB route.
Don’t stress about having to use an installation guide, the fine folks here have made it incredibly easy to follow and get a discourse forum up and going.
