You both have very valid arguments. Cost vs will the new pilot really get into RC or is this just a passing fad?
One very inexpensive way to find out, and less risk than even a cheap RTF, is the Introductory Pilot Program.
I am surprised it doesn't get more mention in this forum.
For those that don't know what the Introductory Pilot Program is, It is a program set up by the AMA to allow people that are interested in flying RC airplanes to get free instruction on a club owned airplane to see if it is right for them before dishing out any money.
The club I fly with has 2 introductory pilot trainers.
Quote from the AMA website:

Intro-Pilot Program
An intro-pilot program is available to all chartered clubs. Qualified pilots from chartered clubs may participate. Instructors can train non-AMA members to fly airplanes during a time period of 60 consecutive days, and students are covered by the liability provisions of the AMA insurance policy. Full details are available from the Membership Department at AMA Headquarters
