SubEthaEdit is awesome, and I bought a copy for ~$45 back in the day. However, because it is expensive and a Mac OS X only desktop application, I have only had opportunity to use it maybe once or twice. :(
$45 is not expensive for anyone in a developed country, specially as a business expense. That's how much you would pay for a decent dinner for one and 2 drinks by the glass.
it's true that this might not be strictly necessary. i could buy 7 etha edits a month or pay rent....and since i only need 1 etha edit forever, it's orders of magnitude less expensive compared to rent.
still, the numbers just tell me why it might be ok to make the purchase. if i threw away 1/7th of rent every month that would add up to a non-trivial amount. so, yeah, it better be worth it.
