Looking for handheld GPS advice

[Sigma]

My approx 15yr old handheld GPS died this week and I am looking for a replacement. I have not kept up with the technology during this time so I thought I would ask here for advice and then add it to my Father's day wishlist.

I am looking for a handheld unit to be used for marking way-points while hunting, fishing, farming, and quadding. I am looking for a unit that is good on batteries, accurate, has an altimeter, area calculator, stores routes, has topo maps and also not too expensive. I am not into geocaching.

I would prefer a larger screen - not too sure about using touch screen (poor eyes and fat fingers) I would also like to be able to download data to my computer.

I have checked out the Canadian Tire, London Drugs, Walmart, and Costco websites but they have a very limited selection. Are there any places in the Edmonton area other than Cabelas that have a selection? I wish there was a store like Calgary's GPS Central where I could go and compare before buying.

Thanks in advance
