The good point would be that you will have an instant collection of (very likely) non-working machines.
Probably 50% of which will be either rubbish titles or ones you are not keen on.
If you are not keen on this 50%, chances are others won't be either unless they can "steal them".
You will likely outlay 20~40K UP FRONT several months in advance and then cross your fingers.
You will have sleepless nights wondering where your goods are, will customs put a hold on my goods as a first time importer and it cost me thousands more? What if the ship sinks? What if pirates seize the ship (don't laugh, this is an optional extra on most shipping insurance policies)? and 200 other worries.
There are very few positives UNLESS (like I said earlier) you are going to do it on a regular basis, you commit to it as a JOB and pour LOTS of money that you have every chance of losing into the venture.
Those who are doing it and making $500~1000 per machine I say good luck to them!! They are earning EVERY CENT!
