Congrats on your 28ga!
I love mine, shoots like a dream.
Not that expensive, when you count the hulls in. Make sure you keep them. If you reload (and I think you should, but it's not for everyone) they are gold (you don't see a lot of them left behind on sg fields). I did a quick check over on ebay and folks are getting ~10 cents a hull. I buy AA for ~$7 bucks a box, so take 2.50 off for the hulls and you have a bargain for quality shells.
