Apart from the portability issue, I don't understand the refractor /reflector debate.
If you want to see images as fine as the finest medium aperture apo -refractor, for a similar price, just put a cardboard mask with an 80mm off axis aperture over your 250mm dob, aligned in between the spider vanes. When you are bored with seeing seeing galaxies and nebulae as fairly featureless blobs, just take off the mask and enjoy the aperture .
Yep I'm a bit of a stirrer, but there is a lot of truth in this.
