I have seen rumples's 18" SDM in action and it is a serious piece of gear. The tracking is very good and for the high level of magnification he does on jupiter, it works very well.
Mel Bartels and those guys have been playing with field derotators for a while and they seem to work.
It must come down to how "serious" you want to do dso photography. Most guys here will image for 5mins, 10 mins, 30 mins and get fantastic results.
I loved the visuals from the large mirror, but would highly recommend you look at Pauls peltier cooling for the sdm. THe cool down time was very quick as opposed to waiting for 8+ hours.
Have fun deciding
