I know I'll catch some flack for this, but...
As to any potential frequency concerns (50hz your side, 60hz mine):
If your loads are resistive, frequency is, essentially, irrelevant. For any inductive loads (motors) you'll get slightly higher RPMs (50 to 60 ups it times 1.2). This matters little for
most devices. For most other home inductive devices, such as transformers (single phase) there are no significant issues.
Obviously devices "timed" by frequency (e.g., motor driven clocks) DO care about line frequency.
That said, don't rule out old US (60hz) Military genset auction items that may be available and, I suspect, dirt cheap.
I base this on the use of AEG (European) kitchen appliances (freezer, fridge, oven [with built-in fan], dishwasher, all rated at 230VAC, 50hz)) in my home for the past 32 years. The dishwasher finally died last year
. So sad...
