I've found that the infrastructure between gas and glow are not too different cost wise. Keep in mind that you will need multiple batteries and a good battery charger. A good charger can run you from $80 to $150. I would suggest a multi battery charger. Mine charges 4 batteries at once and all battery chemistries. You can also look for used equipment. One of my current students got started for about $200 buying his plane and some supplies at a swapmeet and a few other bits of supplies new. Ask around at the club and get one of them to inspect the used equipment first. Cool planes are nice to fly, but while learning that will where off quickly once you just try to fly without crashing. It wont matter what it looks like eventually.
