Hello, my name is Juan and I write you from Costa Rica, I am searching an online robot sensor supplier for a mobile robot that I am building. I have attempted with robotstorehk.com but I have problems with the Paypal buying system, so i am looking for an online supplier that has his own payment system with credit card and in which I can find the sensors I am looking for:

Bend / Flex Sensors (These are very important)
IR sensors for measurement of proximity
Contact sensors for detecting bumps
Microphone
Speaker

Please if you can help me I will be very grateful to you. I check with frecuency this forum but I will be also grateful if you could email me the answer to jlcrespo@rocketmail.com

Thanks very much for your attention
