There are far too many camcorders that produce not only good results but I would say great results, and without knowing your specific needs it would be impossible to suggest just one model. I would suggest going to your local Best Buy® store and talk to a digital imaging expert in the store. Try different models out and choose the one that meets your needs the best. There is also a lot of information on BestBuy.com that could help you in choosing the right camcorder for you, and if you want to read that information you could look here: http://www.bestbuy.com/site/olspage.... I hope this helps!

A refreshed iPhone would be an iPhone that was previously found to be defective, but has since been brought back to like new condition.

You will definitely need an amplifier to use this system since it designed to transmit and receive an audio signal which would then be amplified by an amplifier that fits your needs. The type of amplifier used would depend on what type of signal you are inputting into the amplifier. If this system is for vocals you will need a PA amplifier, for guitar a guitar amplifier, and for bass guitar a bass amplifier. I hope this helps!

You would not be able to connect an iPod touch to the internet in your car, unless your car had a wireless network set up in it.
