www.apartmentratings.com or some similar sites, too.
Here are some helpful hints, too:
* drive by during day and night, b/c neighborhoods that look quite cheery by day can scare the hell out of you by dusk
* check the parking situation; do the cars look junky and rundown? Is the parking lot well lit?
* always get a copy of the lease to look at terms first. Keep in mind also that carpet cleaning CANNOT be deducted from your security - that is illegal in WI if it is normal wear and tear - so make sure that is scratched from your lease. Negotiate and ask about any other things you're unsure of too, (smoking, pets, notice to move, etc.).
It's hard to find a good place at that price but you can if you look hard enough. I've always had better luck w/privately owned places (duplexes).
My last recommendation is to live on the top floor - nothing worse than having someone Riverdance on your head all the time!
Good luck and shop smart
