Please recommend a good shuffling machine
I own this 6-deck shuffling machine. I can highly recommend it for the specific circumstances we purchased it for: shuffling lots (4 decks) of expendable (i.e. cheap to replace) cards. We just run the decks through, cut a few times, and repeat. Say 3 or 4 times. It fed evenly from each side for us, but I could see an identical model not not working as well; it's not like its precision machinery.

We like it because the only real way to shuffle that many cards by hand is to split the deck up into multiple piles to be shuffled by humans and then combined, re-parsed out, and reshuffled. This way is much faster. 

Reasons I would not recommend this machine for your purposes:


it's not worth the trouble to load it for a single deck (although for Munchkin with expansions perhaps it would work)
it also has a tray, although we didn't have problems with it
it's murder on cards (they're technically riffled, but get slammed together so hard the edges start to break down) we replaced the decks fairly frequently
you still have to strip, since this machine only riffles


It looks like there are professional models that riffle and strip, but they're expensive, like $500 instead of the $15 we paid.
