you get what you pay for, that case i would go around and try (especially with a quite low budget) it feels like DX-Racer are best in the class, costs after that to, though
i had a Formula series, but i gave it to my brother when i got the idea to build my own chair... anyways, i personally could have hoped for abit better quality, especially when paying 200e for it
that one are 5 years old, and looks like 25 to be honest, well used though (notice the armrests) they started to look like that after a half year
(my old one)
be wise, and make sure you sit comfortable, especially if you spend many hours in it)
go for a real office chair, that's my suggestion
