We've got SS appliances in the range you're thinking. We bought Frigidaire and got the fridge, range, micro, and dishwasher all for about $2000-$2500, so that's probably the same sort of stuff you're looking at. We've had ours since Feb of last year, so they're about 16 months old.
So far, so good. They do scratch if you happen to use a scrubby sponge by accident on them (oops!), but we haven't had one dent yet. No kiddos around our house, but we are NOT gentle people with our appliances, so maybe you can count my husband as a kid
We really wanted the look and feel of stainless but just couldn't afford the really high end stuff. Here's what we ended up with :
Micro:
Frigidaire Products - PLMV169DC
Range:
30-Inch Freestanding Gas Range (Color: Stainless Steel)
Dishwasher:
Frigidaire Products - FDB1250REC
Unfortunately, I can't seem to find my fridge at the moment, but it's also frigidaire
