thanks for a quick reply.. well dificult question for me.... lets say 500....max...is that any good as I havent got a clue! I dont wont a not so good set up...as I learn very quick. basicaly a digital camera with memory.so I can waste many pics if possible,if need to. It doesnt have to be digital. I just wont to take first class pics..just of lightning as it as always been my passion. the website lightning trigger claims you can get pics like that,but I thought I better ask on here first before I shell out any money. Thanks pat(dogs32)
