I have both the Denon DL-160 and the Audio Technica AT150MLX. Both are available from Amazon. The AT150MLX is almost twice as much money, but I can assure you that it is a much better cartridge. On its own, the DL-160 sounds good, has a nice tonal balance, good bass. But play the AT150MLX for awhile and try to go back to the DL-160 and you'll find that a lot of the music is missing.
My turntable is a Technics SL1210 M5G, but its tonearm's effective mass is pretty close to that of the RB-250, so the compliance/tonearm effective mass should be a similar match.
