parazapper vs ultimate zapper

i just made up my mind and was going to order a parazapper... to my big disappointment, when I went to the site they say that the device is not being sold at the moment due to problemes with the FDA...

Does anyone knows in how long, if ever, parazapper are going to be on sale again?

In the meantime I took a look at the ultimate zapper... it plugs in the main on the wall.
to me this is a benefit as you don't have to worry about changign batteries and polluting, but I can't help thinking about getting electricuted.. surely this is not the case, still...
a bad point about it is that it has alligator clips, does anybody have experience with those, they don't look very stable and secure..

other than that the ultimate zapper claims to be the best zapper out there, they also say that batteries operated zappers are not very effective, they have 100% positive pulsation and a constant wave...

can anyone advace me on this?
or should just grab the ultimate zapper befor also this one is going to be stopped?
