I've been flying one in prep for a rp event im going to do and I must say its absolutely fail. The mines bit is nice but in no way warrants its size and lack of guns, AND the spatial does that so much better.
Its junk might not be so with two more guns but as it is only worth temporary flying for special rp. Stay far away...
Id suggest the council gunboat, even though its got its own problem (huge, i mean xbox huge. Really its a support ship) or the tridente.
