Yeah A5's are very good beginner guns and have the cyclone feed installed already. Other great choices would be tippmann custom 98, tippmann alpha black and the Siera? All of which are highly customizable with many parts on the market.
If you guys are into woodsball or just plain tactical scenario games then those guns are very good choices.
Here's a pic of my set up!
