Depends on which Era / Nationality you are looking for
Bendsinister's Redline miniatures are great for post 1812 French and British. Artillerists well proportioned and good poses. bendsinister.co.uk
GHQ make some very finely detailed ones, but the artillerist poses are very stiff and formal. British, French, Brunswick, Russian, Austrian, Prussian later war stuff. ghqmodels.com
Old Glory make a wider range. I find the wheels too close together for the guns. Have some good limbers, ammunition wagons and supply carts. Sorry no pics.
I haven't used Pendraken but like the photos above. There are more 1805 – 1812 from the looks of the catalog.
I have a few other pieces from Magister Militum, no guns. I find their men a little too chunky and in strange proportions (large heads).
Hope this helps a little.
