Mate you are the king of polar scope polar alignment!
I'd say you get your polar alignment within a gnats hair with that. The rest of us mere mortals are not anywhere near as close. Your setup works really well but the best guiding I ever achieved with my TEC180 was with a MMOAG without a doubt. I found a guide scope on my setup (my guide scope was cheap and could be heavier duty for sure) was a tad unreliable. It would give great guiding one trip and the next a bit off.
1x1 binning on a 16803 chip REALLY shows up the little guiding errors.
C'mon Mike you know you want an OAG!

If you want to have OAG please check the backfocus beforehand. I believe QSI is the only CCD with built in OAG and any other CCD will requite an external OAG which will take some additional backfocus.
TEC flatteners have about 78-85 mm backfocus which leaves little or no space to fit a OAG after the flattener.
