I'm looking to build a simple subscriptions Drupal 7 site. The basic requirement is be able to buy a couple different products and then get recurring payments for the user on a month by month basis OR quarterly OR bi-annually OR annually. Ideally, I'd like some Rules integration but I can probably add this myself too.
In Drupal 7, I haven't had great luck with Ubercart and uc_recurring on a previous project, so I'm looking to switch to something solid that works. I tried MoneyScripts stuff awhile back but it's lack of flexiblity at the time made it hard to use. I looked some at DRupal Commerce and subscriptions but it doesn't seem ready and working yet. I'd be willing to use something 3rd party / external, if it's reliable and the Drupal integration is good.
Any suggestions on best option for a subscription service with Drupal 7?
