Best paintball start-up Marker ?

ive played paintball a number of times before for fun xmas do's birthdays etc and ive been reading abit about the equipments and the game in more depth so now i just need to know what is the best startup marker to use for speedball i think this and now woodball because you can always take a speedball marker onto woodball and do ok but woodball markers like tippmans are to heavy and slow to use well playing speedball correct me if im wrong :P so what would get me the best value marker for the money and does it use HPA because apparently ive heard its much better than CO2 for consistency when shooting. thanks in advance :)
