No. Both circuits on that page are complete and in agreement with advice given on these fora.
That is, just two MOSFETs, no need for a driver transistor in addition like you may have seen used with a relay.
The only comment I would make is that if size is important, you can find smaller MOSFETS, just
-
Be sure to pick logic level devices and
-
A P-FET that can handle your anticipated load.
Others may have part numbers handy.
The diodes in the 2nd circuit are not critical, use a switching diode 1N914 or 1N4148 - the diode he specs is fine also but larger unnecessarily.
Both the larger and the smaller diode will be useful at others times, so if you need a get a bunch don't fret. They are relatively inexpensive.
I'm still on a bunch of 100 1N914-alikes that I got, er, some time ago for a few dollars.
