It just depends on what you are looking for. There are lots of breakdown signaling devices out there for less money. and if all you needs is a strobe for an LZ or something, cheaper options for that as well. But one problem is that these things tend to be abused when used as road side warning devices, and being run over is not unusual. I think the extra cost is worth it, but YMMV. Sometime you do get what you pay for...
