Hi Boz, Any system is not the be all and end all, just like with many other things, when you feel it doesn't perform then you are free to change. What is more important is that you are still a photographer.
Many thanks for the KMP site, which has given me and many others an invaluable source of Pentax information. I'm glad to hear that you will keep it going. Just keep on taking those pictures. Good Luck. Ziggy
