Hey @Alli Welcome to the Forum!
I’ll offer another approach:
If you stage your purchases, it could make getting a nice button box a bit more accessible.
The simucube doesn’t need a button box to function - you can start with a 30 euro rim from ebay and attach it to the quick release and get started racing (you will need pedals, which I believe start at about 100 euro)
This can lower the ‘starting cost’ of a Simucube significantly vs considering a fancy wheel and button box, and if that means you can get one sooner, I think it’s worth considering!
(In the future you’d buy a button box, possibly buying a nicer one than you would have considered originally, and then finally upgrade the wheel rim itself - you’ll then find yourself at a really nice end state that looks and feels fantastic from end to end.)
I wish more people talked about this approach.
When I was first shopping for a direct drive, I bought a different product and skipped the simucube because the ‘wheels were so expensive’. I wish someone would have pulled me aside and shared the advice I am sharing with you - (Had I known I could have gotten a Simucube, pedals and wheel for under $1500USD I believe I would have started with that instead of the other product I spent a year with before finally getting a simucube)
Hope this helps and again, welcome to the community!
