Given the sage advise that others have offered. It really is up to you.
Keeping in mind that Aperture does rule.
In the beginning of this hobby attending Star Parties with others more
experienced will give you a feel for what others use for visual.
I cannot say that I have seen anything but 2" eyepieces being used for
visual with SCTs, never mind the people with Dobs.
Go to Star Parties, ask questions and see what others use... don't worry about small budget add-ons... as they will come. Your accumulated experience is what will be your decision maker.
There are no right or wrong answers...Just try to learn from others
hands-on and you will find you have spent your money well.
If you do decide to go with the smaller size eyepiece a 24mm Televue Panoptic used (don't pay more than $240) and a nice 8-24mm zoom would be a nice start that you could use later with a refractor when the time comes.
A side note: Televue 2" 35mm used Panoptics do come up in our classified section here on CN for almost the same price. That is where I bought mine. It is my finder and absolutely the best EP I have
