One alternative that I like is the "breadboard-like" copper boards from Busboard Prototype Systems. Several of their models have layouts just like solderless breadboards, but are soldered, and so more durable and stable, while leveraging your breadboard design pin-for-pin:

I love these because like many folks, I prototype earliest versions on one or more breadboards and these have the same hole layout, even down to the parallel power and ground rails down the sides. Very convenient and available in several sizes and other configurations.
