Hi Kugan,
there are actually 2 lots of systems here, probably causing you a bit of confusion. There are the systems you can buy without actually joining the members area of the website - once you buy them they are yours to keep and use for as long as you want. The other systems are only available to monthly members, and you don't get the rules to those, only the horses to back or lay, so you will only be able to use them as long as you are a paid member of the site. As for this being the smartest move you've made - that's probably true! We have members here that have been with Keith right from the start almost 5 years ago, and many other long term members - that in itself should be a strong hint that this is the best place to be!
