Hiya - just a word to support you on your search
You will find PGMIII - but you have to be patient. I went looking for ages (six months plus) and then three came up in rapid succession. I bought them all - one for the bike and two spares. Now the horrible bit - AUD$800 plus each for two of them and the other was AUD$450 off that certain auction site sourced out of Japan. And then you take it on faith that they work too..... But stuck the first one in and started on the second kick.

Good luck and good hunting
