For the bees or the beekeeper? Not for the bees, because wood is a far inferior hive material to poly, which gives significantly greater thermal efficiency all year round, reducing bee labour & stores consumption and increasing yields.
In the short term, maybe, but beekeeping is a long game and a few pounds more at the beginning is neither here nor there, so don't be seduced down that dark alley. Efficiency of equipment for the bees and commonality of it for the beekeeper are paramount, but they don't include those factors in an online catalogue.
overbuying if I get an extra brood box
Although you have read a lot, your practical inexperience with equipment will lead you to buy too little and run out of management options early in the season.
Have you any poly nuc boxes? A couple will enable you to nuc the queen and make increase. Split boards are cost-effective tools to make vertical splits for swarm management, and extra broods, frames and foundation will enable that to work. QX? Plastic are a practical mess; buy wood framed stainless steel. Feeders? Abelo poly box feeders are best value in my experience because they can
do five jobs and you won't need to pay for a flimsy ply crownboard.
Some mouse guards (seen them in the field I am setting this up on)
If you were to buy the boxes and roofs but make floors to
JBM's plans you could dispense with the fiddle and expense of mouse guards forever.
If that is your whole list, you're underbuying. Colony expansion will hit you like a tsunami in spring and although you have planned for more than the standard static catalogue spec. of a brood & 2 supers, you have a way to go.
