do any of your friends or family shoot DSLRs?
if yes, it might be beneficial for you to shoot the same brand, as you can borrow/share some lenses and accessories (especially helpful if they have lots of camera gear
😀 for you to test try)
if you're a nature/outdoorsy photographer, the WR (Weather Resistant) pentax K-30 is probably a good choice. It's expected to drop in price in a few months
note: the 18-55 included is not the WR version
edit: 😵 WOW the costco kit actually includes the 18-55 WR...
edit: they changed the description, it's not the WR
if you're ok with spending $900 + tax and then selling the pentax WG-1, it might come out to less than $800 if you need it now though

also available in navy blue and black
or body only, currently cheapest shipped from singapore (the 18-135 is out of your budget though
🙁)

Pentax says the warranty will work in the US as well
otherwise, the nikon d5100 or canon T2i/T3i are both on sale a lot lately, and johnnyrebel's suggestions are all good.
if you don't care for video and want some budget for more lenses and accessories, you can go with older models of DSLRs and still get great results.
The olympus pen epl1-2 have been pretty cheap lately
lately there have been a lot of mirrorless offerings like the nikon J1 except with larger sensors
canon's eos M will be released soon @$800
pentax's k01 is selling for $690 with the DA 40mm XS pancake and natively supports all of
pentax's K mount lenses
