You'll need to be able to knit so you can make a cosy for your teapot! Boom tish!
But seriously, I had a 1999 GSX600 and it was brilliant.
With a bike that old though, you'll be wanting to make sure that the following has been done reasonably recently.
1. Wheel bearing and sprocket carrier bearing.
2. Cush rubbers
3. Steering head bearings
4. Swing arm bushes
5. Check chain and sprockets for wear - chain shouldn't have tight spots and sprockets shouldn't have hooked teeth.
It's oil/air cooled too, so you'll be wanting a decent service history.
Make sure the fairing fasteners are in good nick and check the frame for accident damage - you'll have to take the fairing off to look, but it is definitely worth doing. Look for dents, scrapes, rust, or obvious welds in places that shouldn't need welding. Make sure the oil cooler isn't just a bunch of flattened fins.
If everything is OK, then they are a fine buy. They are the equivalent of an anvil in the biking world. If they're good and looked after they'll do everything you ask, and they'll be fun while doing it.
