Hao, I understand if you need money ... but you still have to be reasonable. Some of us are developers and know how many hours you have invested in this product. It's a great product. On the other hand, it's a relatively small product, in the eyes of most of your customers (or would-be customers). I can almost guarantee that you would sell more copies at something in the $3-5 range than in the $10 range ... which could actually net you more money. You need to ease your product into payware ... not just expect people who have been using it (for free) to pay $10. That's ludicrous. You claim that you have had 20,000 downloads ... do the math ... would you rather 1% of those people pay you $10 ... or 15% or more pay you $3-5? I support the purchasing of software and make it a note to purchase at least one a week ... there are other people out there like me, I am sure of it. But, you need to get realistic in your asking price. =)
