I'm also in the pre-wash camp. Working with reds, I found that an inexpensive Walmart piece did not bleed at all, while a Moda Christmas fabric bled repeatedly through several washes.
Methinks you don't necessarily get what you pay for. I've read comments about Kona solids not all being the same quality depending on where they are sold.
Anyway, it all comes out in the wash, so I wash.
