Hey,
I've had a soft top on my 06 Tacoma for the last 24 hours. I bought it at a local 4 wheel parts parformance center and they matched an internet price. $499.95 out the door. I could've beaten the price online by a few bucks but being able to drive a few miles and stare a person in the face was well worth it. If anyone is looking for parts and they have a 4 wheel parts store nearby, do ask for a price match, it was sweet.

As for the top, it's a Bestop Supertop, and so far I love it. No, it's not a hard top, but neither was I looking for a hard top. The instal was easy and with the side windows there's little compromise to field of view. I like the collapsable aspect and I recognize that nothing will be safe from being stolen in the bed. But, that's where my Border Collie Garth comes in. He loves riding shotgun, and now he can safely ride in the bed. I have the side and rear windows out for the time being and he'll keep anyone from messing with my stuff.
I'd still love to hear from others who have first hand experience with a soft top and I'll keep the forum posted on my experiences with my Bestop.
Enjoy
