Yea, the problem is how little space you have plotted...
I was just looking today on eBay, and you can get an external 8TB drive for only 220 USD... ridiculous. I almost bought one out of principle!
But the good thing too, is that HDDs have great resell value, so even if you buy it and decide you hate BURST, you can always resell for almost the same as what you paid.
I'm thinking I'll pick up one regardless.
But yea, you'll not show on the list until you submit a deadline that shows up... which with such a small amount of plotted space, could take quite some time.
So my suggestion would definitely be to get more space to plot!
Might work out well. If you were going to offer it for .25. I know you can buy an HDD for less the .10 a gig. If you can stay under the average per gig it woukd bring you more I would guess.
How much space do you plan on haveing to offer total?
