I really like the Empress Ecw although I have not painted mine yet... Perry have their own charm too. Probably the two best manufacturers in the smaller 28s range.
Warlords plastic ECW I have something of a love hate relationship with, quite good to paint and convert but accuracy of the kit, is questionable and the trousers are just too baggy. Not really a fan of the metals at all- though a lot of weird faces IMHO.
TAG have a nice 'Thirty Years War' range sculpted by Nick Collier, which is quite good for extra drummers, officers and pikemen.
