There's nothing different with the newer LEDs if you're running it straight from the MR board. You likely just broke the strip and you can run it just fine from the board. For your budget there's not much else you can do and the "add-on" boards for running LEDs that used to be around aren't anymore. Simple conversions aren't running the LED properly, but it works. I say keep it simple! Wire it like the tutorial and have fun.
