Wedding Slideshows

For the past few months I've been contemplating adding another option to our wedding Bells & Bubbles. (as if we didn't offer enough options already) 

I've been tinkering around with wedding slideshows and have ended up with mixed feelings about them.  I personally think they're great keepsakes!  I wish we had one from our wedding.  They're a great way to view and share your wedding pictures besides looking at them one by one on the computer or television.  However, from a business standpoint they take a LOT of time and energy to create.  It took me several days to create a slide to one song.  Not only do I have to figure out the best music for the slideshow I have to time the pictures and transitions to the music.  With that considered they wouldn't be the cheapest option we offered. (or the most expensive)  I am also left to wonder if they're something our clients would be interested in.  Most of the weddings we've photographed have not had a videographer. (there aren't many reasonably priced professionals available)  While my slideshows wouldn't contain actual video from the wedding they do have an almost video feel to them.  

Please feel free to share your thoughts... any insight would be extremely helpful in my decision making process.   For now, I just might have to create one from start to finish and base my decision on the end result.  This should make one of our happy couples VERY happy.
