Today, it's better than it ever was. I mean, almost multiple choices AND enough versions of Shermans to make ALMOST everyone happy. And the RTR's are much better too. Now we don't HAVE to get a Tamiya because most people want instant gratification but then there are those that like to build.
10 years ago there was Tamiya with their 4 tanks and then HL with their TI and Pantiger. Choices were slim and aftermarket parts were even slimmer BUT... the hobby has grown and competition is good for all of us. So lets just make sure we don't bite the hands that feed us and recognize what's laying before us.
Support ALL of them or they will disappear.
