If you want to do mainly visual, are you sure an EQ mount is right for you? As Ray notes, if you are doing imaging then driving via the PC is much more sensible/reliable powerful.
Another option is to use a smartphone or tablet as the handset and use Skysafari, via Skywire or SkyFi. Then you would just do a simple 1-star alignment with your handset, and then rely on Skysafari to do a local sync (which offsets the pointing model based on the nearest synced location). This will be typically a lot more accurate in a given small patch of sky than any type of whole-of-sky 3-star alignment.
I speak from hard-won experience here! When I do AP, I simply use my computer (HS stays in the box). When I do visual, I use a mount in Alt-Az mode, do an initial HS alignment, and drive with my iPad (but leave the HS connected, because it's better for fine-scale positioning of targets within the eyepiece). These combos work brilliantly.
