My domino XL was delivered today with a systainer for the 500, seneca adapter arrives tomorrow, went with that because I probably won't use the bigger dominos as often as I think I will with the 500 set. I do have $500 worth of giftcards to woodcraft, I could buy another systainer, or I could pony up some more money and get the TS 75 which is what I'd really like to get, decisions decisions.
