let's say that everyone has a budget a 100$ for the night
Depends, if you want to sit with 100$ at the table(be able to play with your full 100$ when you go all in) then blinds be 50/1$. You could also decide to sit with less money at once(50$ or 25$) which would be 25/50 or 10/25 penny and when someone loose his 50$ he puts in another 50$.

The 50/1 will last less long and be more stressful but thats up to you
