I would recommend the excalibur vortex, it is a simple design thats very effective. The thing that I like about the vortex the most is the ease and cost of putting my own string on the xbow. I originally purchased a barnett predator xbow and it ate strings and cables for lunch (within about 1/2 archery season practicing often)...It was around $100 for new strings cables and install since I couldnt do it myseld... With the excal you can put a flemish fast flight string on yourself for $14 and about 5 minutes or less! The vortex is louder than the predator but trigger and overall feel of the vortex seems much better to me. The arrow travels so fast that I have never had a problem with a deer jumping the string out to my normal 30-35yard shot. Ultimately its up to you but with the excalibur you will get a lifetime of service out of it and you will be able to do the maintenance yourself.
