what one should i get????

I love the Tactical Alpha Black, personally.

Tippmann is a very reliable company, and they have great customer service --they have sent my friend free parts before when he called about broken parts.

please note that you will have to buy an electronic hopper if you get the egrip, because otherwise balls will chop when you have it on full auto. --that is a huge pain to clean up
you will also go through more balls so it is a lot more expensive then without the egrip
