Pendant Purchase considerations

Looking to buy a pendant.... a cheaper one... considering giving the ebays ones a go around XHC - WHB04B etc... just wandering should i stick to a USB cabled version or go with a USB wireless one ? Or should i put that thought out of my head altogether ?? Any suggestions appreciated or any recommendations on alternatives that work well with Linuxcnc ??


Thanks

I'm using a VistaCNC P4-SE. I would love it to be wireless but I worry a little bit about trusting the wireless connection. On the other hand I'm using a wireless keyboard and mouse with no problems at all. The one advantage to the wired model I have is that the E-Stop button on the pendent is a physical switch. Even if the USB goes nuts the E-Stop still works.
