I'b be one of those people cbreeze... especially with Tamiya paints... I only use Tamiya thinner, use it for my MM Acrylics too... I go both ways, enamel and acrylic. I prefer acrylics though once I got used to them like Scott said.
the only thing I really go out of my way to use enamel on now is a higher gloss finish like the HH-65 Coast Gaurd chopper sitting on my shelf I need to finish... everything else is acrylic.
Recently I got turned on to Vallejo acrylics and I am trying them out but I seem to like them more than the Tamiya, about the same as the MM... they do clean up a lot better and are easier to measure as they are in squeeze bottles you can put out paint by the drop from. Same with the thinner... so it's easy to calculate a ratio.
I suggest the primer as well, a nice clean model, and at LEAST 24 hours drying time before masking...
