Need a suggestion for a decent software protection

Hello

OK, I realize this is a weird question to ask, but I thought this would be the best place to ask it

I have an application that I want to distribute and I'd like some suggestions on the protection to buy and use. I know that no protection is perfect, I'd just like one that would be decent, that is, not very easy to be cracked. My budget is not the greatest (say, around 300USD max), so I wouldn't go for a very expensive protection (i.e. 3000+ USD). An online activation scheme, or an activation based on a key would be all I need. I plan to give it around, but I'd like to have control over its distribution and activation

I was thinking of Armadillo at first, but it seems it's quite easy to crack it. ASProtect looks to be better. What would you guys suggest, given my budget and requirements?

Thanks in advance
