10x50 upgrade to scope

[Russko13]

Hi there have been using my bins for a while now they are a pair of 10x50 Olympus dps1. I have no doubt that next summer il be getting myself a nice big dob around 8" maybe a bit bigger as il be off to dark skies on a regular basis when the weather gets a bit better but have been looking at the this scope to buy for improved views of the lunar surface, Jupiter and deep sky as m42 or m31 in the meantime, would be great to have something a bit more powerful to go with my bins, if i do buy this scope I'd quote like to upgrade the finder to a telrad or erect image 9x50, a 90degree diagnol and a few more eyepieces, can anyone give any advice on this idea!

Oh and just for some more information I was very much up for purchasing the skywatcher startravel 120 but have been put off by the amount of people that have said about lack of eyepiece options for a fast f5 frac
