You got a point but alot if you do enough research on certain products you will be able to find product support that it really good (only on certain none popular yet products). Also not alot of people have a hobby shop by them and do all of there stuff online so it would not matter if a hobby store had them in stock. For example on my Caster, whenever I need a part it takes no longer than 3 days for me to get my part from Caster so support and availability is not a problem with Caster at all for anyone. Most hobby shops take longer than that. I agree with you about info at tracks from others not being able to help too much because nobody has them and about setups and racing info but thats what makes it fun, tuning and setting up yourself to figure out what things do. Now if someone is not mechanically inclined then maybe it would be different. Yes it is easy to copy another's setup sheet but not as fun to experiment. You have all good points.
