Hi, if it were me its an easy choice. Comparatively the SR800 is a more expensive instrument. It may have Bartolini electronics, which I love although it could have Ibanez electronics if its an old one. It's made in Japan (I have had two MIJ Ibanez basses that have both been superb) and it has a set up. It also has had a production run of 25 years so there must be something good about it. No brainer!
Here's a quote: [i][color=#414141][font=Arial, Calibri, Helvetica, sans-serif][size=3]For 25 years the SR800 has given bass players a modern alternative. With its continued popularity, Ibanez is constantly endeavoring to answer the wider needs of a variety of players, at a variety of budgets. But no matter what the specs, the heart is the same-SR continues to excite with its smooth, fast neck, lightweight body, and perfectly matched electronics.[/size][/font][/color][/i]
