I don't do it for the money, but I think it pays for itself :
Based on the above, in about 34 months I have saved $2400, aka about $70 per month or about $840 per year.
From my POV that means I could spend $70 per month on mods and not "lose" any money.
The real "spend" for me has not been money as much as it has been *effort*. If I add that to the equation, then it's probably not worth it. But that's where the hobby part comes in.
