If you like Shostakovich or Prokofiev.... the Jarvi/RSNO recording of Shostakovich 4th Symphony is about the the best one available. Their 10th is one of the best, as is their 7th.
The Prokofiev symphonies with same conductor are very good, the 6th is again about the best available.
The Dvorak symphonies and tone poems they did with Jarvi were also well regarded at the time.
These were all recorded in late 1980's early '90s, since then the orchestra has suffered with top players leaving and unrest, and has been eclipsed somewhat by the BBC Scottish SO especially since Osmo Vanska and Martyn Brabbins got involved there. But hopefully the RSNO will get back on form again, having now appointed a new chief conductor, can't remember his name.
In last few years they have been putting out some recordings on Naxos, Marin Alsop recorded a lot of Samuel Barber with them and quite well received, also Bax symphonies with David Lloyd-Jones and a few Bruckner Symphonies with Georg Tinter. At budget price these are worth investigating.
Overall the Shostakovich 4 and Prokofiev 6 both with Jarvi on Chandos are the best recordings they have done.
