Here is the only problem with "buying" a bow press: The style of the bow has changed so much in the last 7 years that litterally most presses that are even just 2-3 years old cannot be used anymore. Try pressing a Drenalin on just about anything other than an X-press (or a copy of it), or what I am about to show you, and you will end up with a thread on broken limbs on the Drenalin (ever seen those before?). Lots of other bows are the same way. If you want to ruin your bow, you don't have to buy a bow press to do it, you can just dry fire it a whole bunch. Pressing a bow wrong, however, will do just as much if not more damage.

Here is the press I strongly recommened:

They ain't cheap, but they will press absolutely anything, and all it does it put about 1 or 2inches of pressure on the very tips of the limbs (just like drawing the bow does). You can press any kind of bow in this press (except an Onidea and maybe a monster; but all you need for those is two pegs on the wall). You can seriously press a bow with one finger in this press. Its money very well spent.
