The sears tend to wear out int eh newer ones, the quality o them just isn't as good anymore.
besides that they're great. Because of the durability you can feel safe buying a used one so long as it's a few years older.
to clear up what matrix was saying, recently tippmann went from being the most durable markers out, to ... well pretty much the most durable markers out. Sear wear isn't a big problem it's become slightly more common in recent years.
i was talking to a friend of mine who plays regional, and he suggested, since im unsure as to whether i want to stick to arena or woods, i should buy a spyder due to they are (apparently) more versatile. Any arguments or suggestions as to what would be a good beginner spyder gun?
