Definitely another vote for the OEM top. Yeah the Trektop is cool, however, you don't have the luxury of putting the top back up if a sudden rain storm hits you while out and about. The oem soft top is extremely easy to use with a little practice.
Check your local craigslist and see if anyone is selling their's. Many times, people will get the soft top with their hard top as a "dual top" option and they simply don't want the soft top so they sell it. That is where I got mine and I ended up spending $600 for a brand new top that would have costed me close to $1,300 anywhere else. I have heard of some being sold as low as $300 too, so search around.
Another thing to consider is that if you buy from the dealer, the soft top will be in a hundred pieces and the install will take up to five hours from what I have heard. If you get it from a "dual top" option, the top is almost completely assembled and the install should take you no more than an hour.
Just my .02 for the day. I hope this helps.
