I guess there are a few things to consider.
1 - Do you have a budget in mind for these machines ? Keep in mind you will have freight, customs clearance, freight forwarders, Shipping and GST charges.
2 - Will you be keeping all machines in your collection ? Will some be projects for you to restore and sell ?
3 - Do you favor DMD / SS or EMs ?
Sounds like you have an interesting project ahead of you
