The SmartParts Ion is one of the best paintball guns out there on the market. Any skill level in the sport can pick it up and use with no problem at all. From beginner's to even the pro's who get paid to play. The Ion is one of they most customizeable paintball makers in the world. Unlike most paintball guns this one just about ever part you can customize, and find parts for just about anywhere. With that said reminds me of the weight, this maker is so light out of the box i forgot i was holding it. Even with paint and air it still ways less than 4lb, and if you get upgrades or aftermarkets parts they can take off weight to because alot them weight less than the stock part. But as far as performance this marker will blow you away, if you are trying to get into the sport as a rec player or on a team this marker can just about keep up with one's that are upgraded. If your afraid it doesnt shoot fast enough to keep you alive in games then your wrong. Its great on air to, only is it takes compressed air unless you get a part to where it will take c02. But that is a waste of money because c02 is not as good for your gun as compressed air is, so therefore your killing your gun in the long run. Now as far as reliablity goes this gun is the best I have seen. I've had my on for about 3-4years now and just recently cleaned it and lubed it for the first time since I got it brand new. Let me let you know I also played speedball for a year along with just having fun playing on the weekends. I've put at least 30 cases of paint through it and it still worked like its was brand new. So this marker has your back tell the end and will last along time. So dont second guess yourself, get the Ion if you wont, especially for the price you will not regret it.
