I'm looking into building the famous Ball Factory, but have a little hesitation about the motor. Just in looking at prices, the M is at $7.49, the L is at $13.99, and the XL is at $9.99. My first reaction is to just buy the XL since the price seems to be low, but I'm wondering if there is something I'm missing. Is there a reason the XL is cheaper than the L?
While I'm on the topic, I think I'm just going with a battery box for now, to see how much I end up using it. Is there anything else I should pick up? Extensions, etc?
This will be my first GBC, so any other advice is welcome!
