For experimental purposes, taking nootropics / mind-altering compounds during meditation might be cool / useful. As a long-term practice, it is not really beneficial. Consider the main point / purpose of meditation and then see whether adding a compound to make it easier is actually a good idea (it's not). You can create physical changes in the brain with meditation, but use a drug and you aren't seeing the advantages in most cases.
I have found a great Zen meditation course on Zencast: http://www.insightmeditationcenter.org/programs/online-courses/
It is not only an audio course, you can also sign up to work with a meditation teacher who will get on Skype for 30minutes a week to follow your progress.
In the buddhist tradition, it is free and you can make donations as you wish.
I have written about my experience with the course on my blog: http://www.lovelifeproject.com/tag/meditation/
I use the app Lift: https://lift.do/
to log when I meditate. It helps me to make meditation an habit.
It is free as well
I try to just sit still without using props but sometimes I am not in the mood and I use two apps to start my meditation practice:
Omvana who has a library of audio meditation. Some or free, some are not
I have started to practice mindful eating as well recently. Does anybody do it ? Do you recommend some specific exercises or readings ?
