I take it this is a bit of a job for a beginner?

Does it make better sense for a noob such as myself to just buy a chinese entry level scope?

I'm a complete beginner myself, but I just bought a tube from a Skywatcher 250px flextube for use with a.10" mirror. Will have to change the truss length.I bought it from astroboot, they've still got them in stock, 50 pounds.

Here's a 10-ich Dob I made some time ago. The mirror housing is made from thin (1/16") plywood wrapped around a couple of 9mm plywood rings - secondary cage is the same but no thin ply exterior to keep the weight down. Six truss tubes were used rather than the then standard eight. Used TV aerial poles for the truss rodes they were thinner wall than most on-line tubes - again to keep the forward weight down...
