Pros:
More shops available to you.
MSCs provide better support and communication.
Fees start higher.
Many shops require very minimal reports.
Cons:
High upfront cost.
You are on video so less room for error.
You won't get paid for a percentage of your shops due to equipment failure.
The equipment wears out and needs replacement eventually.
A large percentage of shops are one-and-done where you cannot shop them again or the rotation is really long so travel becomes more necessary.
Many of the shops require you to pose as someone with a high income, such as a home buyer in an upscale area, and you may not be able to do them with an old car or pickup.
Many shops require just as much reporting as a written shop.
