yar i live in lahore and liquid poly at hobby lobby is not available till the end of this month -- ive no idea about its shops n karachi--
pilot figures are one of the accessories which ive rarely found in stores in pak-- pilot sizes might also depend on type of plane/type of cockpit/scale of kit etc
if this is your first model--i'll advise you to take baby steps-- buy a kit which is cheep , try to keep finishing of the glue neat , try to attach decals without breaking them, try to assemble landing gear yourself rather that attatching the premade optional landing gear, try to keep canopy clear of glue and finger prints--
you are bound to make mistakes in the first 2 kits , so dont waste much money on them and the accessories
AFTER that you can ventour into more details
