Hey there! I help run a local design agency and we're in desperate need of new computers. We currently work with MacBooks connected to external monitors and it works but they slow down a lot and hurting productivity. Out of the computers Apple sells currently, which is the best value for money, and is it worth buying used/refurbished to save some money? We have an Apple store almost next to us so buying them and getting support is super easy which I particularly like, but their new products are incredibly expensive and I'm not sure if I can justify the cost or not.

What do you reckon?
