Simon Says DIY

Hi,
I am building a Simon Sais Game,
Searching the internet i found 3 DIY's
One is the KIT thing, and that spoils the idea,
The other one i found uses a PICAXE-18 microcontroller wich is not available in egypt, last one i found is ok,
but i wanted to add some more features to the game, A speed control, a reset botton and a 7 segment counter to count the correct moves.

SO please post any ideas, any links and help would be appreciate!
these r the links i found
thank u
The PiCaxe Simon Sais Game

This one is the one i want to improve
