Do you think something like the Oxford Nanopore MinION [0] is a viable alternative, assuming you'd want to do just the sequencing yourself? I suspect most people wouldn't be able to do the prep without proper wet lab training and equipment [1], but the starter kit is $1000 for the device, a single flow cell, and one rapid sequencing kit (SQK-RAD004).
