which eyelash revitaliser is the best

[Olddear]

I have really poor eyelashes. Used revitalash which was great (but expensive) but on a weekend away I lost it. Can anyone suggest a good one?

I've been using Eye Candy XLR8 (chosen purely for the fact that it was half the price of all the others) for the last few weeks as I had stubby, gappy lashes all of a sudden. My lashes are now in very good nick again - I assume down to this stuff.
