I have the same exact issues here in Portugal. Is really hard to find used electronic stuff for sale. Even some simple IC's are hard to find and I have always to search on chinese markets.
This type of equipment is not so easy to order like the ICs and other small pieces of hardware. I will buy, in the next days, an osciloscope from Germany. Fortunatly I can order stuff from EU without paying customs, because if I order a scope from US the agents will be very happy to charge me more than 100€.
About the signal generator I will try to get an old one in my university (I don't need a display on a function gen if I have a scope that can measure the frequency). If I can't get one there I don't know where I could get one for a good price...
