I've ordered a few different 3D metal puzzles. they are sort of funny (sometimes frustrating and patience straining) but rewarding when completed.
This price is only for the Eiffel Tower.
The seller has other metallic puzzle buildings for sale for relatively low prices
Brooklyn Bridge, Empire State Building, Seattle Tower, US$1.44
Ozbargain beware - the listings all say:

Also other restrictions:
If you are a quick temper these puzzles are not suitable for you.
If you are a completist online shopping is not suitable for you.
