I would never consider the Need for Seat option considering the company is blatantly selling illegal versions of dxracer chairs. They have not been an authorized dealer for a few years so any stock they may still have of original chairs are models long outdated, dxracer chairs do not have 'names' they have model numbers and series types plus dxracer does not offer any warranty on the chairs from that site,
I have an embody but wife wants a leap, I use aeron's in the office and I personally preferred the leap over the aeron but obviously the embody is my personal overall pick, only problem is it's 1.4k :P
I have a green Markus currently and it's pretty awesome. Rugged, comfortable, stylish, compact and easy to move. A tad too tall at it's shortest height maybe, but still a great chair that proves you don't need to buy something expensive and covered in padded leather to get comfort from a gaming/task chair.
My problem with the Markus is that it's only 200 bucks, what's the point of getting a discount on that? I know that the higher end chairs such as the leap can go for as much as 200-300 less than the MSRP.
