I guess so, I have some serious favourites, but fortunately they're all cheap. Classical Hoplites, Thureophoroi and Peltastai (Thracian and Hellenic) are some of my favourite infantry. You could virtually build an army around them (and I have!) but it will hardly break the bank doing so. Not hard to access, either, being available all around the Med.

Cavalry-wise I like Hellenistic bodyguard cavalry (particularly the Epirote ones; not so much armour as others, but really good stamina for heavy cavalry), Celtic Leuce Epos/Curepos. Again they're cheap but very effective if you use them right.
