Not really into listening to aircraft Bob but I don't think the Whistler 1010 is suitable; the spec suggests it's FM and – I think – most VHF aircraft chat is AM or USB on HF.
The most important part of the set-up is the antenna. If you visit an airport a whip on a cheap radio will pick up local radio traffic with few problems because the signals are strong. By the time you're 5 miles from the airport, you may only hear what's flying nearby, which may be good enough for you. If not, look for a radio with a socket so you can run coax to an antenna in the clear; a home-made bent-wire dipole will out-perform a whip especially if it's high on a pole. You can also get commercial antennas to fit to a chimney on the roof.
If you're intending to listen at home, and have a PC or laptop available, SDR is a good bet. I've listened to aircraft on HF and VHF with a FunCube Pro and – more flexible – a SDR Play RSP1A, reviewed here. As usual the more dosh the better the SDR, but you don't have to spend loads of money to get good performance.
Rather than scan and stop on active channels like the Whistler, SDR displays a slice of radio bandwidth (132kHz Funcube, up to 10MHz RSP) on screen. You can see visually when channels are active and click on them to listen. Depending on the software it may be possible to listen to more than one channel at a time, and some can scan as well.
A disadvantage of SDR is the computer side – not for everyone! You might prefer a conventional radio with buttons!
Air to ground conversations are extremely terse. When conditions are good I've found HF more interesting. In SW England I've listened to New York taking waypoint reports from aircraft mid-atlantic on about 5MHz ; they were a bit more chatty and quite busy. Another advantage of the SDRs and good aerials is they cover all the frequencies used by aviation from VLF Beacons to UHF military.
Not tried one myself, but upmarket scanners, including Whistler, for sale here. The expensive ones can scan more than aircraft but the extra features may not be needed.
