SYM “wild wolf” and Legend are the same thing.
125 $51000/125R $58000/150R $63000
It will probably be too small for you.

Kymco has the KTR 125/150 $55800 but its very skinny looking.

There are the 150 wannabe cruisers:
Dragfire-

Zing-

Yamaha’s Breeze, if you want a more sporty-looking bike.

Hartford’s HD200S $73000/150s $61000/150T $52000

Hartford’s VR200 $93000/150 $71000

Yamaha SR150 $48000

Prices are from yahoo shopping, so probably higher than if the price you can get if you go ask in a shop.
The first two and the hartford may look kind of small.
The VR200 or SR150 would be good, or one of the cruisers. Though I’m not sure the cruisers are that great to drive around in Taipei traffic.
Part and maintence-wise the SYM Legend will be the easiest. KTR shouldn’t be so hard either as it’s a fairly new bike. Parts are easy to get for the SR150 in Taipei anyway. Other ones I don’t know, esp. the cruisery ones, as some aren’t made anymore(husky/dragfire).
If you’re just going to use it for commuting, it’s not really worth the effort and $$ of getting a motorcycle. Though scooters are “gay looking”, they’re much easier for…everything.
If you’re really set on getting a motorcycle, why don’t you borrow/rent one first for a bit. Bikefarm rents out RZXs for 2600 a month.
