Ok here's my advice. I learned on electric before switching to glow. The one thing that I have learned from doing it this way, is that eventually, you will regret spending all that money on electric when you could have gone glow from the get go. I started three years ago on a plane call the Soarstar (copy of Hobby-Lobby's Wingo), I then had to buy a radio system to go with it and servos. All total, I spent over $250 to get it up in the air. If you are frugal, you can have a very fun, forgiving glow trainer plane for less than this amount.

Example:

World Models Sky Raider Mach I ARF(high wing semi-symmetrica trainer, easy to assemble and flys great) $69.99
Thunder Tiger .40 $65
Futaba or Hitec Sport 4-Channel Radio $120
Total $254.00

If you buy this online from Tower, they always have discount codes that give you so much off a purchase if it totals a certain amount. In fact yesterday, they emailed me with this month's code of $30 off a $199 purchase so you out of pocket total is now $224. This leaves you an extra $76 to buy support equipmnet (glow plug heater, fuel and fuel pump) or possibly upgrade your initial radio purchase (which is always a good idea to buy more radio than you need b/c you will grow into it)

IMO, electric is nice and clean, but it is more expensive than glow.
