I think my biggest thought would be, assuming you had your genome sequenced, what could you do with it? I can think of a lot of theoretical things, but I think every inspection of that genome for something would cost money (possibly/probably more than the cost of sequencing). I may be wrong about that, though.
You can quite easily do stuff like mutation calling and differential gene expression analysis with subsequent gene set enrichment analysis for free on a standard computer. You'd need to know what you're doing of course, but in terms of costs, it's definitely manageable. That's if they provide you the raw data, though, which doesn't seem to be the case with a lot of providers.
