A lot of it depends on what pickups you have (H/H, H/S/H, S/S/S, etc).
My main guitar has two humbuckers and a 3 way strat style switch - so it's very Gibson like, which works for me. I also have a push/pull pot on the tone control which acts as a coil tap on both pickups. When it's engaged, the guitar is somewhat Tele like. This also works for me, especially for clean tones.
So I can get 6 sounds, as opposed to 5 with a Strat style 5 way. Of course, I don't get those "in-between" Strat sounds, but that's OK.
Something maybe to look into is the ToneStyler. It's an analog replacement for your tone control, that shifts the pickup’s resonant frequency and adjusts the treble rolloff point. It has, I believe 16 increments. I've seen some demos of it, and it makes a huge difference in the sound in a very usable and musical way. And it's a drop-in replacement and not very expensive, if I recall correctly.
That might be a cheap and easy way to change it up if your not using your tone control anyway!
