Thanks for all the replys
I have picked up Napoleon's Great Adversary: Archduke Charles and the Austrian Army 1792 - 1814 and volume 2 of John Gill's trilogy on 1809, Thunder on the Danube.
I have painted 2 battalions of Grenz, 3 of line [2 hungarian] and now painting a grenadier battalion.
As I lack an opponent with figures[pete is the slowest painter on the planet, he has been painting the same ancient Indian army for nearly 2 years.]
I have been buying French troops of ebay and another friend is painting more, so far 3 French line battalions, some hussars and dragoons.
Will try March of eagles first with my 10yr old son and pete, then on to Republic to empire.
Thanks again chaps
Keith
