Is .28% good? It could be. But that depends on what other funds are offered. If there are index funds with a .05% expense ratio, you may be able to approximate the target date funds with even lower fees. Or if they're all managed funds with ERs over 1%, then those target date funds could be by far the best choice.
One caveat about the target date funds is that they pretty much assume a normal retirement age. I have no idea how old you are, but if you're retiring 20 years earlier than normal, they may be overweight bonds (or at least they would be for my liking) so you might want to consider picking a fund with a date past your projected retirement.
