i hope you're doing ok after your treatment. im old too but have been lucky so far. i was very tempted to by the zwo/asiair route but lack of funds made me have to use an old macbook running windows i still wanted to keep my options open so i got a zwo guide camera just in case. im still using a stock dslr, and that is my next upgrade, one day
i have the swsa gti too and while im sure its not the greatest mount in the world, it seems more than capable at least for us noobs. i really dislike the altitude adjustment bolt, it always seems to have a dead spot where it turns freely just as im getting polar alignment bang on. works well with nina though so far.
