I am looking for Door/Window sensors on Ali Express but feeling unsure about which to choose. Anybody who can provide some links to a sensor that works well and looks good?

Based on the supported devices list:

Door/Window sensors:
Low Budget Chinese Door/Window detectors
based on EV1527 & HX2262 (If timing resistor present, any resistor value will work)
Intertechno ITM-100
KAKU AMST-606 door/window sensor (seperate signals for open and close)
Home Easy HE852
CHACON DIO 54781 (seperate signals for open and close)
COCO (separate signals for open and close)
Evology door/window contact sensor
ELMES CTX3H, CTX4H
Chuango: among others DWC-100 Door sensor, DWC-102 Door sensor
Avidsen Door contact 102359
X10 security sensors
Atlantic's security sensors
Sigmatek door contact
MC145026
Lobeco NX-450N-I
LightwaveRF Contact Switch

You should be able to use most of the Ali Express contacts as long as they are 433mhz and use a 1527 or 2262 chipset..
