I definitely reccomend the Super Cub. Haven't flown the nitro planes or the Exceed cub, but I have seen some negative posts here about nitroplanes customer service. Btw, I have bought a couple Super Cubs on e-bay for less than $100, including shipping. Just search "hobbyzone", but you need to pay close attention to shipping cost and description of plane. I like to deal with Hobbe-mart because their descriptions are accurate and they will make good on any problem they didn't list. I have my own formula that might help you if you decide to buy one this way.
First, since a new Super Cub is only $160 shipped from Hobbyzone, I will not spend more than $130 for one at e-bay. This is including shipping and I will only go this high if it is listed as NIB or only having light dings in wing or fuse. So if the shipping is $25, my max bid is going to be $105. I figure any part that goes bad right away is probably $30 or less so I'm not taking much of a risk if I buy one this way.
Second, if hobbe-mart or who ever lists it as having a bad servo, bad rx, no battery included, etc., I go to hobbyzone.com and find the cost of the items I would have to purchase to fix the plane. I deduct this cost plus shipping cost from $130 to determine what my maximum bid will be. For example, an rx for the Super cub is $26 and shipping is about $4, so if the plane is listed as having a bad rx and the shipping is $25, then my max bid is going to be $75 to $80 max. Of course many people don't think this way and spend too much in my opinion, so you may have to bid on two or three planes before you win one, but it has worked for me several times. Good luck on what ever you get, but lets hope it is a Super Cub!!
