Blah...the factory sucks in my opinion for the 4th and 5th generation accords. They don't tilt (up or down...only open from side to side) so you can't keep it slightly cracked open to vent out air. I don't know where you live, but in California...we have California Sunroofs and they do a really good job (they in fact do aftermarket sunroofs for various dealers here). The brand they use is AESCE (something like that) for the power sunroofs. $1400 will get you a power sunroof, really nice sunroof and in fact I might have them put one in my Tundra. The pop ones are around $900 I believe from them.

Here's an interesting read about sunroofs.
