Martinc,
I own the Leica now and like it but it is too bulky for bow hunting and does not fit well in my shirt pocket.
I believe the new Leupold Laser Rangefinders are going to change the entire way we hunters view and use rangefinders. The RX-II is made for the bowhunter in my opinion. With a built in Inclinometer, True Ballistic Range reading capability, scan mode, rain mode, etc, etc... There are way too many features to list but once again in my opinion this is a must look at if you are in the market for a new rangefinder. I believe the suggested retail is $319. They should be out very soon; I have looked through the RX-I but have not been able to get my hands on the RX-II.
If you want to read more about all the features stop by your local sporting good store and pick up the Leupold 2006 optics catalogue.
Good luck in 06',
