Just resell everything. Yes. Otherwise, you are doing it wrong.
Sometimes, 'reselling' is the best option. I have a brand new L360. Prints fast and high quality.
Guess what, sometimes I have another shop print wraps for me. They have a couple Latex 3000's. They can print the same quality at least 4 times as fast. Sometimes time is money. I can tie my printer up for 2 days printing several wraps or I can have them do it in 1 day, while I'm making money on other jobs.
No one is saying you should always outsource, but there are times it's the smart choice.
