Interesting reasoning
If you only need the odd vehicle 20mm would be much cheaper
I find 20mm cheaper because I need odd vehicles that would cost a flipping fortune in 28mm, or are simply not made. Also, with an average cost of 5-6 euros for a unmdade second hand 1/72 kit it is perfect for my limited income.
Hi Johan yes I guess I need to explain that. Vehicle for vehicle you are right, the smaller you go in scale the cheaper it will be. The problem for me was that in 1/72 I felt I wanted to play company or battalion level games so I always needed loads of each vehicle. Over 4 years of making and painting model tanks, trucks and infantry and I never properly finished a single army. It just became about collecting. Sometimes even I got sick at how much I was spending.
So the problem was really about me getting into a rut with 1/72, not the scale itself.
With 28mm that compulsion/temptation is just not there. A dozen figures, a truck and a tank and I am satisfied. I might even finish a project some day soon!
