The 21,000 POIs in my Vista right now take up only 4.7 mb of space. One of the best things is that POIs take up surprisingly minimal memory space. I use the first one on the list for my Vista HCx it essentially downloads a cache webpage (including log entries) onto the GPS. Here is a brief waypoint v POI comparison. Data such as cache name cache owner last four attempts hint coords cache size, type, etc. GSAK has about 60 different data parameters that can be placed in either the title or description. Kirs&Alex, the downside for you is you need to be a premium member to create pocket queries, which is a batch of 500 waypoints then have a program such as GSAK reconfigure the waypoints by putting about 44 characters in the title and 88 in the description/comment section of each waypoint. Having the webpage available on your handheld GPS is not useful?! Get the Venture HCx! (unless you think you need an electronic compass/altimeter, in which case get the Summit HCx.) There also are other options for purchasing online. You can currently buy a Venture HCx for about $110 from Amazon or about $130 from OffRoute. The eTrexH requires a seperate, serial cable and to use it, you might need to get a USB adapter unless your computer has a serial port that will accept it. Also, if you are going to cache with the unit, you will want to be able to connect the unit to your computer. It is easier to use and has more functions. Given the choice between the two units you mentioned, without question, I would purchase the Venture HCx. It isn't all that useful for caching and, if you have a unit with a geocache function, it won't treat POI's as geocaches and, thus, you wouldn't be able to read the note from the compass page while searching for a cache. I think you need a unit that accepts a memory card to do the points of interest thing. You can do that online after you purchase the unit. Can you help me figure out what you mean? I got confused by the 'upgrade to 2.50' bit couldn't find any mention of upgrade.
