welcome, you will find us all helpful and also VERY honest so be prepared and take it like we want to help you and not get rid of you
my first advice is DO NOT BUY, read as many posts as you can , use the search function and see what has been previously said ( check the post date as that matters to how up to date it is )
once you have some ground rules knowledge then purchase something, post an appraisal and see what the response is.
the answer will most likely be $10
but you will get some good answers
once again welcome
