I agree with everything what folk have said already... especially Roo!! :o :lol:
I'm a strat-man, but it doesn't sound like you really want one - except you want some of the tones it'll do and nothing else can really do them...
... that is going to haunt you :lol:
If you've got the spare cash to do it, and can justify it to yourself, or the missus/who-ever, then I would say get one. But do a LOT of trying first, like others are saying.
My current #1 guitar is a CIJ Fender Strat, I tried over 20 that day. A Highway 1 almost got my money early on, but the Japanese one I chose beat everything hands down - Mexicans, US, other CIJs, everything...
To try and make you feel better: I've got a couple of guitars that are in the "not getting played much" category at the moment, including my #1 strat, because I'm almost exclusively playing teles recently. But I wouldn't part with any of them - they're set up and ready to produce the sounds I've configured them for, all different, and when the mood takes me and I pick one up for an hour or two, and every single one of them inspires love and joy in me!
If you're going for it, don't just "buy a strat" - find a strat (or strat-type instrument) that speaks to you personally and buy it. Then spend some time with it to find out what it does for you and how to "talk" with it. After that, even if it isn't your main instrument, it'll always be there for those "mmmm... strat maybe?" moments :D
