I think TP1 was $30 or $40 when I bought it and it continues to serve me well. I believe in supporting developers, but $120-$240 to have some transitions for a year doesn't pencil out. Honestly it's been years since I've even tried TP2, maybe installing and unlocking is simpler now. I own Transition Pack 2, but the transitions aren't worth the hassle of installing and unlocking it when I renew my computer. If it is in the Common -> Plugins folder or something like that it just works. Last time I saw Film Impact mucking around with their licensing I archived the CS6 version of transition pack 1. It's just nice to own some things and not think about them. I go months and months without using them then occasionally they're useful.
$10/mo for their Essentials collection and no options to buy forever? I used to recommend Transition Pack 1 all the time, but I'll think twice before recommending a subscription to anyone.
