You might want to take a look at the following devices:

Lattice Semi - MachXO
Lattice Semi - Lattice XP / XP2
Altera - Cyclone II / III
Xilinx - Spartan 3A/AN
Silicon Blue - iCE 65

The MachXO looks to be exactly what you are after, although I don't
know what they cost. The Lattice tools come with an Synplify OEM
bundled, but I don't know what they cost or if older versions are
available for free. Hope that helps
