I've never seen the Redoubt figures in person, so can't really comment.
I have actually visited their premises, which is a pretty small unit and I think they just had the one spinning machine on the go.
They are in Eastbourne which is about 20miles from me.
Their stuff is ok - I think it varies a bit from range to range, and what used to get me was their website was poor. It has been improving though.
They should be at Salute in London at the end of March.
As to
Foundry, and rufus mentioned their postage charges, - they have a definite sales strategy designed to get you to buy in bulk.
Their 'deals' of 60 foot, or 30 cavalry are usually postage free, and they also do discounted sales when you can buy two or three of these deals for more reductions.
Foundry have a very large catalogue, and they actually rotate the availability of some ranges. I usually create a list of stuff I want from them and buy once a year.
The other thing to do is get together with mates and do a bulk buy together.
However with the advent of Warlord Games over here, and Wargames Factory in the US, and GW's growing plastics kits, we may be seeing a seed change in mini supply .............
