first question, whats ebook? second, you have a good point"just use the free stuff on the internet" thats great, but learning it for yourself. and having it right there when you need it is very conveinent. and theres some people who like to learn more than just the basic stuff. with your logic why dont people just stop going to school and figure everything out over the internet,lol. third mine only cost me $24.00 plus $3.49 shipping. not $40.00. you say they have them at tower hobbis for that much. what a jip. i never really liked tower anyway. they dont even advertise losi products in there catolog, lol. anyway i think the books well worth it, but hey your entitiled to your opinion.
