For Strat single coils, Ilitch dummy coils do a good job. The official product is super expensive for what it is but it's really simple to DIY, since it's a large air coil with a few turns of thick wire... The only problem is to place it: the guitar needs to be routed and / or to receive a giant backplate.
A crude dummy coil can work in a decent way if it has the proper specs and is placed in an optimal way. It's even easier to DIY than an Ilitch coil since it can be obtained from a cheapo single coil with plastic bobbin, whose magnet(s) has/have been pulled off.
Of course, stack or rails pickups are another option, among others (Lace Sensors, Music Man active noise reduction circuit and so on)
I've many of these solutions in my own guitars : they have all their pros and cons.
Side note: TriSonic single coils are less noisy than Fender PU's - and there's Strat sized TriSonic's for anyone who would appreciate their glassy tone.
