Recommended shops in SLS (kinda like CP style ones):
Cybermind (But higher than average price)
I personally would stay away from Video Po (5th Floor SLS). Their customer service aren't stellar...among other non-positive stuff.
Stay away like the plague:
Shops than are manned by ****(partly or otherwise)...not discrimating but that's the trend in simlim. Coincidence, or something I guess. (What's ****? Well...their ancestors came from somewhere south of the tallest peak)
Shops that give out leaflets screaming stuff like $599 FAST P4!!! in super large bold text, etc. Commonly given out at escalators...throw them away!
Beware, there are a lot of AP style shops in sls too... your carrot head okay...
If in doubt, COME BACK AND ASK! Just say u decide to go home and think it over lor.
