That's a good price for the refurb and I'd do that. Even on Ebay you might fetch that for a working refurb, maybe more.

The x50v is nice, but I haven't tried it so I can't comment if it locks up less often.

My Toshiba 805 has the same issue with having to be within 10 feet of the base station. My HP rx3115 works like your normal 100 foot range.
