ebay 4 relay module less than one buck per relay

Wow! $2.89 !!! That's a great price! But my preference is for the 5v versions. Those I have run directly off the I/O pins of the Arduino. I've also noticed a newer design floating around on eBay. I can't be sure but just from the pictures and the look of the silkscreen I think they're different. Just the idea of being able to carry 10 amps at 30 volts makes these a great choice for the trains.
