Depending on your level of skill at painting, check out Empress Miniatures below.
empressminiatures.com/userimages/procart42.htm
Pros:
1) Historically accurate.
2) Slim, well proportioned, and have a good number of musketeers (mostly with the Oxford Army) without rests.
3) Headgear is mostly wool caps.
4) Probably the best detailed ECW range I have seen.
5) Lots and lots of varied cavalry.
Cons:
1) Price: They are on the expensive side.
2) Most of the range focuses on the early years of the war(s) so most musketeers have rests.
3) They can be difficult to paint if trying to paint everything one sees.
4) They do not have any Scottish or Irish Troops, which has kept me from purchasing more from them.
Below is a link to some fantastic photos. The review is fair if someone is trying to achieve this level of detail. I myself am not at this level, so the issue of painting is not an issue for me.

In summery, for me the pros outweigh the cons.
