I am also informing myself about RL at the moment and checking out what is available as I really disliked the tea last time, and could never drink enough to reach the recommended amount.

I was recently reading on another forum about Blackmores changing their label, and now their recommended dosage is 3 tablets 5-6 times a day (it is up on their website too). That's 15-18 tablets a day!! Anyway, it seems that they say this much because the recommended max dosage per day is 2.4g, and their tablets are only 300mg.
I have done a bit of searching and found that other brands that have RL tablets (in Aus) are Natures Own (500mg), Herbs of Gold (2g tablet) and Natures Sunshine (360mg).
I think I shall take the Herbs of Gold, it is very cheap in comparison to Blackmores and only 1-2 tabs per day!
