If you want my advice, you guys want the Slow Stick. As a flyer who's been at this for a little while, the Slow Stick is the best to learn on for the money out there.
If you want to read more on R/C flying, I highly recommend MrVW's recommendation of the Parkflyers forum at www.rcgroups.com (where I post as "pfm" BTW). Looking around there, the Slow Stick is the plane of choice due to price, ease of construction, easy flying characteristics, and durability. For now anyway.
www.allerc.com are a nice company to deal with.
For batteries, I highly recommend the excellent deals at
http://www.bydusa.com. You can pick up two 8.4V 1000mAh NIMH packs for $26 from them... that's the usual price for one pack everywhere else. And these packs work wonderfully with a Slow Stick.
Personally, I think you can go cheaper on the charger than a Triton. I'd rather have 4 packs that I charged at home on a cheap slow charger to take with me to fly than have a great charger and one pack and have to wait while it charges. Beyond a bunch of battery packs, in my opinion, if there's anywhere that I'd recommend spending extra money, it's the transmitter.
For some more fun, pick up an Aiptek Pencam 1.3MP digital camera from Wallmart for $60-70 and attach it to your Slow Stick, trigger it from the plane, and take aerial photos. See my
website for aerial photos from a Slow Stick.
Also, for those who are worried about destroying their planes... well that happens. Nearly always you can fix the plane with a little tape and epoxy. If not, then you are out $35 for a new Slow Stick (although I have crashed mine a dozen times and it's ok). Occassionally the gears in the servos strip and you have to buy replacements (about $4). Sometimes the motor shaft gets bent and you have to rebend it. About the biggest danger is losing the plane... but that's easy as long as you don't fly at sunset or on a really windy day.
No matter what, I would recommend practicing using the Slow Flyer model on FMS (the Free Model Simulator) which can be downloaded
here.
