I played a gig once in a fairly big hall and the supplied backline was a Hartke 410 Transporter and a Hartke HA head, I can't recall which model. The Transporter's a lightweight on a budget version of the XL cab, so probably not as good sounding, but I really liked it. Not a lot of bottom end but clear and punchy.
I'm a fan of Hartke gear in general. If it's within your budget I don't think you'll be disappointed. As others have said, Ashdown, Peavey, Trace Elliot. The usual suspects. It's all good gear and you can buy in the classifieds on here with confidence.
