I've recently bought 4 indo Dats from my LFS as i'm a regular there they do me a deal on them they say: 1x dat £12.99, 2x £24.00 or 4x Dat £40. I am thinkin gabout getting some more Dats and being a teenager i don't get much income, my parents give me £7 a week. So they don't have too many Dats left instore so do you think i'd be better getting another 2? 4 would save more money in the long run but if they sell out they might not get any more in. And would i be better off with a group of 6 Dats at 1.5-2" or a group of 8 dats at the same sizes?
