Thanks OncTech for taking the time to post the details. I actually have found some models that are retailed here in UK and they come with OCR software but I cannot find any reviews for them (although I had time to make only a cursory search online). Hence, I want to hear from actual users. I'm contemplating to buy one to use when I go on field work for my research. I'll find the time to check out Brookstone thoroughly.

Many thanks again.
