Personally, I hope the price stays low so I can keep buying every-other week.
Realistically, without a name brand supporting you publically or some more great news through testing it will remain an uphill battle. I find your stock funny because it doesn't seem to over-react to market flucuations - it hardly budges often.
$4 is not a bad target but there will have to be some firm support to make that move and stick there. For now, $1.50-$2 would be a more resonable price.
