Product review (5 stars): Standard 4 prong dry plug.
I bought this plug from Amazon to save a few bucks.  It seems to be a standard plug which I connected to the dryer and wall with no problems.  I'd suggest buying a longer cable if your dryer has its cable attachments at the bottom.  The price isn't that different, but the convenience of a little slack in the cable is worth it.

The only tricky thing is the shipping.  Keep an eye on how much it cost to ship, as it may double the cost of getting the cable.  Otherwise, despite the added cost of shipping, I saved about $9 and a trip to the local home improvement store.
