The Maverick Et-732 is hard to beat! I've had one for a few years now. The range is great, and I've only had to change the batteries once.
Where it fails is in programing the alarms. That part is a bit of a pain, but once you get the hang of it, it's OK.
As far as getting something now to get you by... Head to Lowes, Home Depot, Wal-Mart, etc. They have a basic inexpensive (around $15) thermometer with a probe that's fine. It doesn't have bluetooth remote and only one probe, but they work and are nice to have as a spare.
For instant read thermometers, I like the DeltaTRAK brand. I have the 11063 model. It's plenty fast enough, very accurate, has the thinner step-down style probe (like the more expensive brands), priced around $17 - $20 and it is NSF approved! They are what my wife says Wal-Mart uses in their deli for taking temps to keep the health inspectors happy.
