Low risk entry into CPLD/FPGA design?
If what you need is simple i.e. definitely at the logic/cpld end of the spectrum and not the fpga-processing end, then have a look at Silego greenpak.

They are really fast to get going, with schematic design, 5V single supply operation, and analog functions (vref, comparators, oscillators)

If what you want to do is learn fpga's, VHDL, etc, they aren't what you want.
