I currently have an AT90EDT, of which I have no complaints except its massive weight and not-quite-Feathertouch focuser, and an SV80ED (doublet), which has a lot more sins (lots of CA out of focus and even in-focus, a not-so-good focuser, etc).
However my skills aren't so great that these scopes don't meet my expectations. But I have always been curious about "premium" stuff, but have been unwilling to put out the $6000-odd to get an AP130EDF or similar (used).
It seems that the least costly "premium" optics is the Lomo 80mm. These got for $1200 to $1300 give or take. I can flip my SV80ED and AT90EDT and get the Lomo.
Does that make sense?
I got the SV80ED as a fancy guide scope, and also as a not-so-good imaging scope that I can put on my Star Adventurer - the AT90EDT is just too darn heavy for the little mount.
I mostly image with the AT90EDT - so in theory it's not much better than the Lomo 80mm. I also have an 8" reflector that I use for imaging (believe it or not, with a Paracorr, that reflector equals the AT90EDT for imaging at my pixel scale).
