Another conv. top thread, input needed!

[nautiquelfe]

HEY guys I need a reputable source for a convertible top for my boxster. I'm interested in the glass option but not for $1000. There are several vendors on ebay selling tops for $400+/-. I don't wanna get ripped off so just asking to see if anyone has had a good experience w/ any of these. I would really like the grey top. Which grey came from the factory as there are 2? Anyone gotta good install spread sheet? I'm not afraid to try this myself but would like to be familiar w/ the process before starting. MY car is a 99 and the back plastic has several cracks. Thanks for info, or help.
