Will any RF keyboard?

Im totally new to this multiboxing thing. But ive tried to read as much info as possible on these forums and gatherd some great info and advice(thx to all pro multiboxing ppl sharing advice). So i do wanna try this out to see if i would like it and if it would work well with the new upcoming WAR game. Ive decided to go the route of using an wirless RF keyboard to begin with. So to my question. Will all of the current wirless RF keyboards work(if so il buy the cheapest)? I tried to get some info from the retailers of the products, but they seem to have no clue :).

I used to hardware multibox in DAoC and early on in WoW using 1 wireless keyboard synched to the same channel on all computers and I know the one super cheap one I ended up using got flakey all the time with missing key strokes. It worked well enough that I never replaced them but at times it got very annoying. I would recomend getting a nice keyboard and contacting the manufacturer about buying the extra recievers. Personally if I ever went back to hardware multiboxing I would just go the vectra keyboard replicator route.

Thx for the replies. I called both logitech and microsoft here in sweden to try see if i could order just the recivers but got an negative reply from both. Guess its diffrent here in sweden :). I guess il just have to order multiple keyboard/mouse sets. Il go for logitech as you recomended.

I bought Logitech RF mice separately from my Linkworld LK-1000 wireless keyboards, so that's also an option.
