ODC 420, foam seat or inflatable?

[Gibbyutah]

Where is a good place to get a fatcat tube? I too am looking to get a tube and this will be my first one and this forum has been very helpful. I just don't think I know enough about float tubes to make an educated purchase. From the Creeks company's website you can get the 420 for $149 which seems like a good deal.

Do I need to worry too much about the denier rating for a tube? I know the higher the number the better.

Thanks
