I have an OMP Grip, bought it when it was on clearance couple years ago thru OMP America. The seat, bracket, and slider all for less than $700 shipped. seat base was bought separately from another vendor, for $120 I think.

The OMP fits me very well, I'm 5'6" around 180lb with a 34-36" waist depends on jeans. I drive from Houston to College Station for autoX every once in awhile and the seat is perfectly fine for me.

I just bought a kirkracing rollbar from a member, and looking for a 6pt harness now. I've been using the stock seatbelts and it works so far. My car is only driven to/from autoX/HPDE now.
