I agree - as with anything, you get what you pay for. I had planned to get a pair of the WO bv's at about $299 or thereabouts. But the guys at Andrews didn't get back to me as they said they would re availability, so I bought the Stellarvue ones from Peter at SDM instead.
These were $275, but they come with a pair of EPs AND a couple of extender tube thingies in case the bv won't come to focus. And they are fantastic on moon and planets, and I thought they were pretty spectacular on dso's as well. For me, I wouldn't be buying the $99 ones. It just isn't enough for a decent quality item.
Just me 2c
