First its important to note that a POE (802.3af complaint) switch should be able to supply upto 15.4W per port while a POE+ (802.3at compliant) switch can supply 30.8W of power per port. A good switch should be able to supply almost near to a multiple of these power ratings for as many PoE ports they feature.
Second most devices that work on PoE like IP camera, Video phone, IP Phone, small extension switch and common AP needs only PoE and not PoE+. Only very high end AP (with multiple antennas and radios plus high end CPU) or high end PTZ camera (which anyways are gross overkill for home use) will need PoE+. This is as things stand today (2016 beginning)
So the recommendation is that once you have decided to go for a switch buy the cheaper and more commonly available PoE switch and if you run into a device which needs PoE+ in near future, just use the supplied PoE+ injector or buy one.
