I went for the OWS figures, I really like them. The only negative thing I would say is that they don't do a mounted generals set. Instead I bought some of their FPW French generals. Unfortunately they are a bit smaller, you don't notice when they are next to infantry, but when you put them next to the GPW cavalry….
I haven't bought the warships yet, but I did pick up a couple of Peter Pigs' ACW naval guns for shore batteries.
I also got Maverick Models to do some Chilean flags.
Like you intend Blake, I went with 16 figure battalions on four bases.
I might go back and paint a few skirmishers, but am not sure about those. Plus, I still have a couple of Gatling guns to paint up….
I am going to use the Neil Thomas C19 rules, as I'm getting old. :)
I reckon with the dozen infantry and two cavalry units I have for each side, I can refight Tacna. While this may be a bit of a slugfest, I like the fact it is the last battle with the Bolivian army fighting alongside the Peruvians.
The book published by Caliver on the subject is excellent…

A lot cheaper, the Osprey is a good intro, but the illustrations are nowhere near as good as the Caliver book.

Also, thanks to Armand, I ended up looking up the war on Chilean Google and found some great illustrations (reminiscent of Blandford books).Lots of info out there (although it became apparent on the forums how much a lot of South Americans hate us!).
And of course, Outpost have a very useful guide on their site.
