Totch,
I went through the same delema not too long ago. Which program, which PDA, which operating system, etc.
I needed to determine which OS first since it needed to be user friendly, supported, and available. I know windows based OS's first so thats what I went with. Where as the Palm OS is different. At least that is what my bro-in-law told me when he offered to give me one of his Palms....he's dripping in $ compared to me. But, I was already feeling overwelmed with trying to get into this stuff. Thus my decison to go to a Windows based OS.
I then decided I wanted a dedicated pocket pc for LRH only. That way I 1)wasn't breaking the bank and 2) if it went down, it was only thing to go down and not my phone, GPS, internet, etc. I read, start to finish, Gerald Perry's EXBAL site and the Field Firing Solutions web site. Actually conversed, 1st via email, then via phone with Gerald and then the developer of FFS (can't remember his name at the moment). Gerald suggested I talk to the owner of the company which sells the ACI in Colorado, since he has extensive experience with both programs. I did and I settled on EXBAL; not because he talked me into it, but for my purposes, EXBAL made sense.
I then started looking at pocket pc's on Amazon.com and their customer reviews. I settled on the iPAQ 2210or 2215. The only difference is one was retailed and the other was not retailed. Simple, effective, not too old or expensive. I then started watching Ebay and settled on a few different 2210's. The bidding began. It took me about 2 weeks but I finally won a used 2210 which seemed practically new. It cost me $110 plus $8 shipping. In addition to the standard battery, which so far has been great, it came with a huge 900 mhz battery which will be the backup for hunting. I then ordered the dual pack from EXBAL and the rest is history. I love it!
