OK, I'm selling off a 40's vintage Gibson Lap Steel and matching amp to invest in some decent studio monitors. I'm figuring I'll have in the ball park of $800 - $1000 dollars to spend.

I've heard good things about the Mackies, Events, etc. I'm thinking, since I tend to buy and hold (read: I need these things to last for years)... I would be happier in the long run with a pair of Passive monitors, and a used amp - I like the idea if the amp goes, I don't have to replace the monitors as well. The only drawback I can see is if the amp and monitors don't match up well balance/eq wise.

What is a good/great combo to look into?

Make and model of amp?

Make and model of speakers (monitors)?

Thanks!
