Without knowing your gaming systems and tolerence for graphics, I can't say much.
People have recommended some older titles, so I'd suggest Legend of Legaia or Legend of Dragoon. They're both PSOne titles and will probably be hard to find unless they release them as PSOne classics on PSN. Also, even upon finding one, they might be expensive. I recently saw Legend of Dragoon on sale for $50. Yeah, a PSOne game on sell in 2011 for $50.
The Suikoden series are great. Suikoden 2 is largely considered one of the best in the series. And if, you have data from the first game (with all 108 characters recruited and alive) you can actually get the hero from it as a party member.
More modern games you might wanna try Valkeria Chronicles or even White Knight Chronicles. Though I don't think either is the strongest JRPG. In Valeria Chronicles defense, that largely due to the odd but cool combat mechanic.
