See if you can find the 298(last years).I have no idea what the year cycle is in Asia(ours starts in April for audio). But new models might be coming...???
You may not upgrade in the next year. But next 5 years, sure.The 199 can be upgraded in pieces(in 5 years, another new AVR, keep the speakers). The rest, the AVR and subwoofer would need upgraded together.
