Looking for opinions

[steelerfan]

I have posted in the new coaches section but was advised to put a post here as well.

What is the best field 308, 620 or something else. What do people prefer and why?

Is there anywhere to buy pro teams besides e-bay- Is there someone reliable on e-bay that any of you have purchased from.

Any advice for someone looking to buy a new field and players for the first time in over 20 years?

Thanks in advance for all replies!
