Malaina and all, Below is the original message from Mike May when Sendero first announced the availability of the Holux M-1000. I think if Jim were to chime in on the differences, between the Holux GPSlim236 and the Holux M-1000, he might ssay that he might not even think about even going back as there is a significant difference between the two receivers. [gps-talkusers] Announcing Holux M1000 Sendero is constantly testing various GPS receivers. We have been using the Holux M1000 for several months and have now switched from the 236 to the M1000. We do not have the M1000 modified at all. You can purchase it on-line for around $50 plus shipping and tax if applicable. We now ship the M1000 with new GPS packages. It of course comes with a custom case so you can easily put it on a shoulder strap. It works fine at the pedestrian speeds, something we tested a lot. Its major benefit is its battery life and greater sensitivity. It will acquire faster and pick up better among buildings or within single story buildings. It is almost exactly the same size as the 236. It has a slide switch for power and uses the same charger and battery as the 236. The battery life seems to be about double that of the 236. I am currently in New York to be on Good Morning America live Tuesday morning. This is a pretty good test bed for this new receiver. I believe the Sendero price is $99 for Sendero users. Sheila will know for sure. I like it a lot. Michael G. May CEO Sendero Group Crashing Through by Robert Kurson now available.
