Welcome to Gaia! ::

well i dont really favor those guns but some r good. I i had to get one i would get a tippman 98 custom. they are sooo reliable and easy to use and mantain. you can also get alot of upgrades for it.

that gun is about the same as the veiwloader triton ll The triton costs about $30 for the gun, and $60 for the same package as the pirrana R6.

so, I'd just check the stats and see which one is better.

the Triton ll does 10 BPS, double trigger...

if you play alot, I wouldn't buy it, I'd get something with an electronic trigger, like the mr1, or the VL charger.

the MR1 is sopose to have leaking problems though. and I've never tried the Charger, but it is sopose to have a brass bolt that can pop easy.

if you need a tough gun, I'd check out the tippmann 98 custom pros, if they're under $140 or so. otherwise you could also check the BT-4 Combat, they shoot far, are under $100, and don't usually jam.
they're a little heavy like, 1lbs heavier than a normal gun.

I look into the spyders, you can order a vs2 or vs3 for under $150.00, but with a tank, this is going to be over your price range. the cheapest gun would be a vlTriton, after that would probably be the spyder MR1(woodsball) or the apyder vs1 (speedball)

for a little bit more, you could get an a-5 or some other tippman, or for speedball, you could go twards the ION or an older dye.
