The current line of budget Chinese binoviewers are all basically the same. There are small differences between the different models but the optics are supposed to be the same. I have the Burgess unit which is supposed to have a little bit more clear aperture than the rest (and I can confirm it takes 19mm Panoptics without vignetting), but it does have those stupid nylon screws too.
I noticed that Andrews were advertising binoviewers for under $300 in S&T. But the William Optics unit from Frontier Optics with 2 eyepieces for $350 is probably the best buy and it should work well in your scope.
