Sounds good! I suggest you use COMC to kick things off seems to be plenty there at good prices (can still make offers though to get them at an even better price!)
I personally haven't shipped an order yet but I have nearly 100 cards waiting to be shipped... going on others experiences it can take anywhere from 3-6 weeks? Might wanna check with Josh (nichj99)
Why not do both? Have Teague as your main PC player..but nothing stops you from also picking up the odd Longley. Someone here might be able to correct me but I don't think Longley has very many cards out there and from what I have seen they are pretty cheap.
I only suggest both players because Longley way your first option, something you wanted to do
