People tend to get little nervous about security now that the media has found it be such a "fun" story, and they blow it way out of proportion. I travel a lot with high end electronics and it can be done without too much trouble.
Checking larger gear on can make things easier, you don't have to carry it, but has it's inherent risk... The baggage handlers don't know what's in there and they will treat it like any other bag, rough. Pack well. If I am checking camera gear I always use a high end case like something from Pelican. It's huge and heavy duty but I trust my gear is protected. It will not, however keep it from being lost. Be sure whatever you pack has no prohibited substances and you'll have no trouble.
For something smaller carrying on board will let you make sure it gets there with you. Again, it goes without saying that what you pack can't be on the prohibited list. That said, pack so you can easily take the item out for inspection. While the screeners might not know what you've got, it's easy to show them and explain it. Have everything you need to operate it with you in case they ask you to turn it on. Arrive a little early to allow for this. Be curtious. They aren't going to confiscate anything that's not prohibited.
In spite of the media hype screening is not much more than a minor inconvenience unless you let it get to you. A little patience and preparation will get you and your kit through with no headaches. Hey, sometimes it's even fun to show off a cool gadget to the folks at security, have fun with it.
