Hi Howard and Welcome,
This is a question that will have been asked many, many times on here and other Forums. At the end of the day you are just going to have to try as many different types as you can until you find what suits can I gently steer you towards the 'Search' function on here as I can guarantee there will be many discussions had on this subject in the past. It will be a good place to start at this stage
Regards
Paul
