I have extensive experience and success on SA. It takes time, effort and a lot of vetting. If you do not enjoy the hunt it is not for you. If you treat Sugar Babies like providers it will not work. I used a date/hookup type approach for example lunch or dinner followed by a naughty hook up at my place. For the most part, I do not provide leads on Sugar Babies. SA is completely YMMV. It's get your own Sugar Baby
The membership is $90 per month. For me the Sugar Baby "allowance" winds up being somewhat more than what I would pay a provider but I find it very much well worth the extra money. I find most Sugar babies come and go but I have three who I have know for over a year and still see.
There is a section for Sugar Daddy'n on ECCIE Worldwide called Sugardaddy Discussions. I suggest you go there. Syster John's discussions are a must read.
