Hi and welcome. There is lots of info in the library (link up top) and the search will help answer lots of questions. A good place to start is probably away from ebay and amazon as there are too many shoddy products on there and starting out many people get caught this way. Any of the site vendors will have quality products you know will be good and perform for you. The classifieds is another good place to look for used items. Good luck with the hunting. Ed
