I still own a few nitro and gas planes, but the only time they have run in the past 2-3 years is on the driveway. I fire them up every 6 months or so to keep them in running order, just in case I get the itch to fly one. Two thirds of my hangar is now electric, mostly Eflite 450 and 15 size. The key is to pick a size or two and stick with it, I only use 3 different sizes of LiPo packs and have enough of each size for more than an hour flight time for each size pack without recharging anything (All of my packs are from HobbyKing and did not break the bank.). I also have a LiPo TX pack, so that is no issue either. You just have to decide if your nitros are something you want to hang on to. You could always convert them to electric as well. I have recently begun to consider converting a few of my 40-size nitros, the only problem is the size no being schoolyard friendly like my other electrics. It really all boils down to what YOU want to do, each option has pros and cons.
