Hi All, this is my first post here. I am looking for my first gps. I see Walmart has the Go 630 on for $98. I also read its becuase their discontinued. Is this a good buy at this price? Will it be useless in a year? I know this is a Tomtom forum, but if this one is no good, maybe someone can direct me to a tomtom or other brand that suits me. I would like, text to speech, spoken street names, exspeeding speed limit warnings, touch screen of course, 4.3 screen, auto re-routing. Thats my main features I think, There are some deals for under $100 locally right now on models like the Garmin 255W. IS this a comparible model?
