I rarely pay for software that I use only once in a blue moon, or software that is stupidly expensive for no reason - with that being said Mirc is only 20 bucks a lifetime. All future versions of mirc can take your code. You never have to buy it again.

I use it daily and has pretty much since its inception. It's one of the few "no brainer" decisions for purchasing I have done.

Skip pizza one night and toss the $20 bucks towards Khaled. It will also save you from the 5 second wait staring at the nag screen every day that you've had to endure for the past few years :)
