WWW.Wirelessnwifi.com has a great sale on right now till the end of the year. Buy a MBR1000 and get a CTR-350 for free.
I used the PHS-300 this year and was very happy with the results. The PHS-300 has a battery that lasts a couple of hours. I used it a couple of times in restaurants with no wi-fi and once in a hotel that had a broken wi-fi. I highly recommend it.

I don’t see where the MBR1000 has a provision for an external cellular antenna. I believe you still need a card that has one.

It's kind of expensive, but if you have the money to spare they work pretty well. As the documentation shows, it works phones and data cards, if that's what David is referring to.
