Getting a LEUP isnt really that hard, just expensive, if your used to dealing with govt types and thier regulations. My dad does that kind of thing for a living (well, not explosives, he actually sees that forests are being well-managed and all that stuff, so hes pretty used to all sorts of annoying regulations), so it wasnt too hard for him.
The magazine costs upwards of $200, and the LEUP itself is $100, and lasts for 3 years, when you have to renew it, for $50. So you would be paying about $350 (shipping is a LOT on those big magazines), plus the relaod case, plus the motor. So if you used an N2000 (or something) you would be paying upwards of $1000 for the LEUP, motor and reload case.
Plus whatever you spent for the rocket.
This sure aint cheap!!!
As they say whenever someone certs at CMASS: "Welcome to high power! Open up your wallet!!!"
