I have purchased several phones on eBay and all have been as described.
Make sure it is a quad band if you travel to other than CR. Also i would recommend getting a qwerty keyboard, especially if you drink (like I do). It makes sending messages much, much easier.
My recommendation would be a Samsung i607 (around $35.00) on e-bay. I would buy it locked, and then buy the unlock code also sold on e-bay. The locked phones seem to go for about $20-$30 less, the code is under three dollars, and they send it to you in a couple of hours. Even a computer moron like me was able to unlock one.

health & happiness to all............
A member PM'd me about this phone. He stated that he couldn't find a new one for under $70.00. I should have mentioned that the $ 35.00 is for a used phone. I have bough a couple and both worked very well, with no major scrtches, or marks.Sorry I should have made this more clear.
