Bob if it was me, I'd seriously consider listing them individually because the Search engines will pick up the titles better.
That being said, I also see why you want to list them as a set.
Here is how I would do it:
I would take out the + sign (like you already have)
Set the attribute price as the actual price (i.e. ball 3.99, bowl 23.99, lamp 33.99, mirror 49.99, etc.) Set it so the base price dot is purple (no X) and put the price as 0.00 in the listing. If you do it this way, it will still show 'starting at 3.99'
The it will show up like this (only with the checkboxes instead of a dropdown box)
http://www.jdcandlesupply...th=15&products_id=139Set the sort order for them so they are listed by price lowest to highest (there's a place to do that same place you set the prices).
I really like the way it looks with the checkboxes and I think that will be the least confusing for the buyers.
I would make sure to specify that is 3.99 per ball and you might consider adding an option/attribute to buy the whole set at a slight discount for x amount.
