If they drop the price to $800 I'm in, but unless it is that low (and I think others will agree) I am happy with my factory top. It can be removed anywhere at any time in about 5 minutes.
Hell, I removed it at my roadtrip destination in Lake Tahoe, and drove around the lake, then put in back on for the ride back home (8 hours).
If you want a Cayman, which this top will make your car look like permanently. For 5K more than a new Boxster and this top, you can just buy a Cayman. Plus, I think the zientops only fit the 987.
Just my $0.02.
