I'd say a barrel upgrade, but the stock isn't bad.
Great for beginners.
A bit awkward to hold.
Uses much CO2.
Bad paint will be horribly innaccurate.
This was the first gun I had bought, and actually used. I got a Brass Eagle Talon Ghost for X-mas a few years back, but I didn't ever use it 'cause the cocking handle broke the second time I tested it! Anyways, I bought this gun at Wal-Mart for $59, along with a 9 oz. CO2 tank, which brought the grand total up to about $90, which isn't bad at all. Since I already had a mask, and a friend let me have a VL 200 hopper, I was set. I went out to my local field, and played my first game with this marker, and boy was I impressed. At first, I was a little apprehensive, since a lot of the guys out there had 'cockers and Tippmans, even a couple Intimidators, but once I got into the action, I was very happy. I was shooting some competition paint my friend and I had bought, and it shot nicely. I didn't chop any balls, and I was hitting where I was shooting a good distance down the field. The only thing that bothered me was the fact that I had to keep getting air at the end of each match, and I was shooting less than a hopper full of paint. Luckily, the field I was at had the option to purchase all-day air.
The second time I went out with this gun, I shot some two-year old Brass Eagle paint I found in my closet, left over from when I got that Talon I mentioned earlier. Amazingly, I chopped maybe two balls that whole day, and it wasn't the 2-year old paint, either! I bought some Blue Streak paint from Wal-Mart (DO NOT BUY BLUE STREAK!), and shot it that day, as well, and it went all over the place. Needless to say, bad paint doesn't fare very well in this marker with the stock barrel.
Overall, for it's price, this is an excellent marker. Anybody who is new to the sport, and doesn't exactly know if they want to get into it hardcore, or doesn't know if they'll have the time to go out, the Marauder is a great choice. I'd say slap a new barrel onto it (which'll cost you more than the marker itself!), and grab a 20 oz. tank, and you've got a marker that'll allow you to play with the big boys on the field. I would not, however, recommend this to somebody who has a great deal of money to spend, and is serious about playing or participating in tournament action, since there are much better guns available for twice this price.
