If you are converting .wav to .mp3 you are definitely one sophisticated grandma.
The Fuze will record from its FM, but you are dependent on the quality of the reception. And all that conversion is going to get tedious.
Here’s what I suggest instead: do it on your computer with Dar.fm.
It is a TIVO-like recorder for radio onto your hard drive. Price: FREE. Pick Adult Contemporary or whatever you want as your music genre. Then transfer the mp3s to any player you want. The Fuze has excellent sound and battery life, and its advantage over the doPi players, besides price and FM on the go, is that it has a card slot for additional storage.
Last I looked, you could still find the real Fuze at Toys R Us for about $69. Probably elsewhere too.
Also, I’ve never used it, but you might want to look into SlotRadio, a microSD card with 1000 songs for about $35. If they are the songs you want, it might be worth it to you. It’s obviously compatible with the Fuze.
