Well my other hobby is astronomy - what relevance has that I hear you cry - well I could say exactly what you are saying here about astronomy magazines, all pushing equipment costed in the £1000's all crying the same about the quality of the articles and lack of youngsters coming into the hobby.
For my sins I edit and publish our club magazine, costings are expensive - we were quoted £600 to produce 100 copies of our magazine - in the end it was cheaper to buy our own printer and pay for the inks, half the published price and we have the printer for the next issue too. prior to that I would do the printing at work for free (with an acknowledgement).
The big problem is getting articles for magazines, people nowadays go on forums like this and document their progress online, then dont feel the need to get it together to put in print, we used to manage 4 issues a year, now we are down to 1, 50% of the issue is now sent electronically (reducing costs considerably).
I agree with a lot of the comments here, provision has to be made to make it easy for youngsters to get into hobbies (any hobby) articles are needed to help newcomers get going (especially the ones that recieved a new boat / kit for christmas).
