Thanks for all the feedback guys…i seem to have graviatetd to SPI…alot of API is very indepth and hard for me as a newcomer to get to grips with. YIP is ok but i don't feel much research and love goes into it. From my little expereince SPI seems to sit in the middle, easy to read but well researched. They also have the best site…www.spionline.com.au – i might keep reading all three for a couple more months to get a better understanding and then see who gets my hard earned money! :o)
