I don't think AIDA64 costs much, but I think there is lack of purchasing options.
For example, I would prefer that there is a "one-and-done" purchase available for an increased price point that allows me to have AIDA64 for a lifetime of updates.
AIDA64 standard price: $60
AIDA64 lifetime license (or per major upgrade version i.e., v7.0 -> v8.0: $180
And then I would like to see a subscription-based model.
AIDA64 - daily - $5
AIDA64 - weekly - $15
AIDA64 - monthly - $30
Then you could have the pricing options be discounted of course from those dates forward depending on how many days, weeks, or months a user purchases.
