Please bear in mind that a number of these boards don't have an ethernet
connector. I bought the DE-1 and it's a great board apart from that, but
ageing as suggested. However, the board you buy must depend on how close a
fit you need to the bitstreams available or how competent you think you
are/might be with the tools in reconfiguring for a different target board.

You can continue to use AHDL but just like any lower level language, its
proprietary to the Altera tool chain, may need work to move between chip
families, and means you will have to do almost all the work yourself. There
is very little AHDL code available for download. So you are cutting
yourself off from the rest of the world where the formally standardized
tools VHDL and Verilog have largely taken over from proprietary languages
like AHDL.
I was going to say that there is no "parameter passing" in VHDL. You
define an entity and then connect it to a higher level entity, but looking
in the help this isn't true. I also struggled with this when I was building
a "Baby Baby" as I wanted to have different types of output device and have
conditional synthesis but this does not appear to be supported.

And if you are going to learn an FPGA development
language look at
SystemVerilog/Verilog, OpenCL, or VHDL. Certainly not AHDL. It was bad
even when it was new. It does not get better with age.
I'll go back to schematic entry before I touch them.
They FUCK! Don
