How do you shuffle your tiles without damaging them?

Any recommendations for tile towers?

I think Meepledrone uses the standard cardboard one out of The Tower expansion - as do I. Cundco sell them separately for a very reasonable price. I like the idea of two for really big games but only have one myself since all my tiles easily fit in that.

Yes, I use the standard cardboard tower. I have 2 C1 and 2 C2 towers just in case but I could never use more than one of them in a game.

I remember asking for more data on the tile tower not long after I first joined - http://www.carcassonnecentral.com/community/index.php?topic=4485.msg65953#msg65953
