Grab a nice piece of driftwood
Yeah personally I'd rather go for a bit of natural wood. It's free & easy to obtain, looks natural (what with being from nature & that...), has different thicknesses, textures etc over its length, & are perfect for a shedding snake. If the branch gets soiled, chuck it out & put in a new one. I don't even bother suspending mine, I just cut them to size so they go from the corner of the floor to the diagonally opposite corner at the ceiling. Position them in a way the won't twist or slip & voila. No need to soak it, cook it, treat it etc (although if using driftwood as longqi said, it may pay to soak it to get rid of any salt in it), just clean off any dirt, loose bark, trim off twigs etc & you're ready to go.
I like ones that are fairly thick, with nice solid forks in them, my Bredl's practically live in their branches. Personally I can't be bothered stuffing around gluing, drilling, cutting, coating etc something that'll still look obviously man made, when I can just whack in a big stick.
Still, horses for courses, if you're after the satisfaction of creating something yourself, that's awesome & good luck with it, I'm sure your snake will use it just as much.
