Orion XT10 vs Zhumell 10 inch?

I am an astronomy newb, and instead of buying a crappy cheap telescope I have been using binos and saving for quite a while now and I am debating the Orion xt10 or the Zhumell 10 inch. I definately want a Dob and everyone talks about the XT scopes as great products, however the Zhumell has very similar specs and of course the same size aperture. I have an opportunity to save about $50 on the Zhumell right now. Does anybody have any input on either brand or the specific scopes I mentioned? On either do you recommend that I have a professional put it together? I have heard that Orion's instructions are vague and leave some things out.
