Rambling post, apologies in advance.
Short answer: take it, depending on the price.
My first light impressions of mine:
It's been my primary scope this year for nighttime observing. I even used it for some fun DSO imaging this year:
For this year, I decided to shelve a C11EdgeHD and its quirks (Is the blurry image from seeing? Collimation?) in favor of the TMB-152 for imaging the planets (I can at least say it's mostly the seeing!). I'm not the best planetary imager, but I'm pretty satisfied with what I got.
I'm pleased as punch with what this scope is showing and imaging. In our light-polluted backyard globs are disappointing visually (the C11 eats those for lunch), but what the TMB does show it shows magnificently!
One recent visual impression of Mars: at about 384x (12.5 Ortho, 4x Powermate) through mediocre to good seeing, I could still recognize Sinus Meridiani easily (had to look that feature up!). The only thing marring my experience was floaters. But the view of Mars was great.
It's also been a great scope for tight doubles. I've occasionally surfed the double star database on my AP1200GTO, and it's pretty cool checking out those stars - and seeing Airy disks! That said, I've had no luck splitting Antares or Sirius with this yet.
Not sure what a fair price would be. I got mine for what I felt was a pretty fair one!
