Just assess your needs. You need to guide, focus and capture subs. Period. I've used Neb 2,3 then 4 to capture subs. I still use PHD1 to guide. I focus with the client included with my sharpcap focuser (ASCOM) or my fingers which don't run on a monthly subscription. If you're happy with simple tools there are alternate choices. If you want a complete software suite that does it all then some and also makes coffee after a successful meridian flip then you don't complain about the subscription.
