you'll get flamed by the CC crowd for considering 3A seats fyi
Obviously high end, name brand seats would be best (attract the most positive attention)...but it may not be necessary
My buddy just bought a cheap seat from JC Whitney and I was very surprised at how high quality it is. The bolsters feel fantastic and it feels rock solid. Ive tried eGay seats, NRG seats, and Tenzo R, this JC Whitney seat felt better than any of them.

They are $159 each, not sure how they will hold up long term but no seat is perfect
