I just sent mine to Frank Spencer down in Florida for, "re-stuffing". I'll let everybody how the project comes out. $75 vs $500 - I figured it was worth the shot.
i have a TS and really like it. i also had a hassle free purchase. having said that, i'd go with a corbin unless TS has fixed the issue they were having with broken seat pans and their horrible customer service. you can read through some past threads on here to see what i'm talking about.
now if you can get a used TS seat from someone on here i wouldn't hesitate one bit. they are really nice.
