I still have my much loved (once) TS-700 which had been extensively modified, to try and compete with later generation radios.
It's very dated by the standards of modern rigs, and huge, heavy and under powered (10w O/P) for mobile operation.
From memory the 290A wasn't that popular in it's day, and personally I'd avoid first generation radios with digital circuitry. The Yaesu FT 480 was also pretty bad.
My advice would be to save up a bit and go for something more recent. Unless you are really into retro radios :-)
