Looking at ur profile location, there is no physical shop located near the area, the closest is in KL or Damansara. Im from Subang Jaya as well and whenever i want to buy some kits i just order it online, save the hassle of driving to KL or Damansara also save petrol n headache finding parking.

which SF are you talking bout? PG, MG, NG, etc????? Since u said ur'll a newbie avoid PG, especially PG SF not worth ur money. MG well depends on the version as well, normal 1 should be bout 180 or so, blink-blink is bout 250, the extra blink-blink-blink-blink ver is bout 350. NG u can get at below 100.
