"I've been toying with the idea of buying PS2 or GameBoy Advanced SP (or both). Seems just when I'm ready to buy one or the other..."

The GBA/SP has some fabulous RPG's. Because my old eyes can not see the Gameboy screen, I bought a Gamecube and a Gameboy Player. The latter lets you play Gameboy games on a TV. Great device. Some of the great games: Sword of Mana, Final Fantasy Tactics Advance, the Fire Emblems. And, with a Gamecube, you can play the only Zelda I have ever played, the Wind Waker. Check it out.
