If you have lower margins then you're vulnerable to bring scammed or just anything going wrong. You need to balance all the numbers and decide if it is worthwhile even being in the business you're in.
That's the thing it's not. This is purely a hobby. If I factor in hours spent that I could have spent working it's a big fat red in any accounting book.
But I like refurbing consoles and customizing them and I need someplace for them to go haha. Having what I consider my "artwork" stolen is what stings the most.
