spool yourself or at the shop?

[rogersmith]

So I have things organized than minus my one drop shot set up with mono, everything else sports either 30lb or 50/65lb braid. Thinking about getting a line winder and some big spools and doing it at home. Do folks spool themselves or have a shop do it? Math is not my strong suit, but I'm thinking the big spool at home has to be cheaper....
