It looks to me as if these have no purpose. For $7, I can get a Nite Finder and hit 70+ feet. For $15, I can get a Max Shot and hit 130+ feet. For $30, I can get a Longshot and hit 100+ feet with an awesome rate of fire. These are all cheaper options than a $42 "Tagball" gun that only hits 70 feet. They are all better options. Therefore, Tagball guns are not a reasonable option for the average Nerfer, and will not appear in many arsenals.
I agree that the price tag (if that is indeed the price) is steep but my interest isn't in 'bang for the buck' - its the adventure/risk of modding something new (i.e. different from the status quo). Personally, I could give a rat's ass about all the blasters people get boners over once they come out (e.g. the Maverick, the Longshot, Spidey/Venom dart tag set) because everyone and their grandma is working on modding it. I'm glad people are shelling out $$ and investing time/creativity in modding them but I don't want to bother with them (most of the time).
I'm really more interested in the ammo than the blaster but how people should spend their money is only of concern to the spender. If I recall, people said the ERTL pump shotgun was overpriced but I know of a few people who'd swear by them (myself included). Anyway, this thread wasn't intended as a "what is your opinion on this blaster" thread. It was (as indicated in the subheader) more of an "can anyone tell me anything about this" thread.
I'm not the "average nerfer", nor is my arsenal.
