I got my BT-4 for $100. My friend got a 98c for $150. I find them the EXACT same gun. BT4 is the way to go for Woodsball. I owned both the guns before, and I prefer the BT-4.. It's odd to, because there basically the same gun. Both built for accurecy. Speed, well, not so much for, but you get use to the single trigger. I say the BT-4 due to the fact you wont be upgraded the guns much. I hope I helped
