for $400 i think you can do beter than both
i have no assoc with
www.astronomyalive but they have a 6" dob on sale at the moment for 300 + change - cheaper than an 8" dobsonian mounted reflector - & a fair bit better than the two celestron scopes mentioned..
the dob mount is much easier for beginners -stay away from cheap EQ mounts unless photography is on your list of things to try- if you try like you would have to upgrade the mounts lsited below anyway
you can whack the 6" ube on a good EQ mount later like an eq5
i did get a secondhand astroalive scope once 12" dob - the included ep;s were actually reasonable - some you get are terrible
they are melb based though -so cost may be a factor
