yep, buy yourself any decently cabled set of jumper leads dont worry about spike protection. better yet go get a set made up with welders cable ad the sort of clamps posted up elsewhere in this thread.
The only ones that offer any real protection are the ones that have "polarity protection" and require you to have both sides connected before they will complete the connection in the module. Of course these have a "bypass" switch in them to allow you to over ride the dead battery sides detection and protection. Which makes it just as easy to make the kind of mistake that can cause damage as youd do by reverse connecting the old school leads.
IF you want to be really safe about it. Buy one of the battery tank jump starters packs and forget the jumperleads entirely.
As drivesafe will probably say next (and while I have my own reasons for having a different procedure than him I support what he will say next)
so with my psychic hat on drive safe will say something along the lines of
"They do it to avert degradation of their own wallets thickness and to prevent those willing to be ignorant of real fact from having sufficient desire to be come knowledgeable enough to question the sellers motives."
There's a big difference between want and need and if you can justify to someone that they "need" what you want them to want over the top of what they really want then they'll buy almost anything.
What you need is a pair of 16-20mm square cables with some 500A clamps and a demo on how to jump a variety of car configurations appropriately.
