I've seen them for around $25. Try shopping around a little bit. Quadratec sometimes thinks they have some kind of a monopoly, and overcharge on some things. I always check ebay, and amazon first.
I've been real happy with the Bestop bikini and have several over the years. Good price too and I can get in the top color to match the Desert Sand color also.
X2 for JPS first line.
I have the best top bikini, picked it up last Jan at 4Wheel Parts for 35 and change out the door. It has held up well on all my wheeling trips so far.
