It is time to buy? A friend of mine is walking away from the hobby (I tried to talk him out of it, believe me) and is looking to sell a good condition Orion XT8 Dobsonian with a R&P focuser installed, and a single-speed Orion Crayford focuser that could be attached if the opening for the focuser was expanded about 1/4". Comes with a finder and a couple of eyepieces, but nothing special there. He wants what he put into it a couple years ago… $190. If you're interested or know of someone who is, let me know.
