The $15 shufflers are complete junk. You have to run the cards through it several times to get a decent shuffle and that ends up taking 5 times as long as just doing it by hand. There is one option worth looking at if you can't get a casino shuffler - it's this one:

It's not on the market yet but apparently it will do a dealer shuffle (3 riffles, strips and a cut) in 30 seconds and unlike the $15 model it's 100% automatic. And it can be flush-mounted on your table. Price? $480 apparently.
