I do... If you ever want to try one, I'd recommend Hasegawa's 1/200 range. So well enginered you can build/paint/decal them in sub-sections (wings, fuselage, engines, undercarriage) before final assembly with PVA glue. They have most of the main players in the field, except the larger Airbus planes...
A bit more intricate are Revell's 1/144 models such as Airbus A330/A340, B747-400, Beluga, Fokker 100, RJ85, 737 last generation. Their older kits are not as good (A300, A310).
Stay away from Heller's 1/125 kits and Airfix's 1/144 until you get a bit more experience.
As far as liveries, there's never been any better time to model airliners..! Check this site to know what's available!
