As a Neonate, my opinion probably won't count for much, and the GTP enthusiasts will howl me down, but I'm game to stick my head up!!
GTP's are probably one of the most spectacular I've seen in my short life as a herper, but they don't DO anything - I've seen a few now, but I've yet to see one actually move!
Look great, expensive, but not much fun!!! (Like some men I've known)!!
