my advise would be to try some.
if you live in reading i would say get your parents to take you to weekend warriors this sunday as it's a walkon day (people with their own gats day) then ask around and see if you can try a few.
(obladeo is going to be there)
im going to be around on the saturday aswell as durajim with our markers. if you want you can try ours out and see what you like. then i can give suggestions based on the style you like best.
or you can always go for:
ion
slg
pmr 2nd hand
epiphany 2nd hand
mini 2nd hand
g3
pirahna pmi if you're desperate
my suggestion straight from off tho is to go with obladeo with his epiphany (depending on how much he's selling it for)
