if building your own only word of advice for you is make sure its super sturdy, ESPECIALLY where your press will be bolted down, it can't be too strong!
my bench is a piece of heavy coutnertop with cabinets underneath and the inital bench setup was just that with my press attacherd with some long screws, 2 case resizings later (yes 2 pices of brass) the press tore clean off the countertop, then we reinforced it with even bigger screws which lasted 2 minutes and 10 more rounds,

, finally gave up and grabbed a piece of 5/8 thick steel flatbar from the garage drilled it and bolted the press to that with 1/4 inch bolts, then attached the bar to the countertop wih BIG lag bolts, then further reinforced the countertop with more big screws into the wall and such,
i guess my point is you gotta BOLT THAT SUcKER DOWN

resizine some cases requires a far amount of pull on the handle and repeated flexing of your bench cuases stuf too loosen off and belive me having to stop and repair your bench 3 times per reloading session is annoying!
Heres some pics of my reloading room:
(And no i dont store my primers and power like that i just organized it up quick for the photoshoot
Bolted down good and some .303 british cases ready to be loaded
And this tube i rigged up off my press to catch spent primers and funnel them through the cupboard to a collection box inside
