You all may already be aware but Lindberg is well on it's way to re-releasing their Gloster Gladiator, Fairey Flycatcher, Hawker Fury Mk. 1, Bristol Boxkite, and the AVRO triplane - these are all great kits, made originally by Inpact/Pyro/Life-Like.
A long, long time ago I bought Lindberg's original Curtiss Jenny, and the new version is better molded. Hopefully the new re-releases will be too. Follow this link to Lindberg's website -
The Official Website of Lindberg Models - Unassembled Plastic Model Kits of All Kinds! Vehicles, Airplanes, Cars, Trucks, Boats, Submarines, Military Vehicles, Dinosaurs, Aliens, UFOs, Transparent Man
Williams Brothers is also being resurrected and have released a number of their kits, with more to come - here is the link to their site -
Williams Brothers - HO Scale Model Aircraft & Cars - R/C & Railroad Accessories
The listed prices for the kits seem pretty reasonable to me.
