I, too, prefer brushed varnish.
My method: First (and sometimes second, for heavy-duty and large pewter miniatures), I apply a coat of Nerchau Rubens Acrylic Varnish. It´s an artists brand which I bought at my local crafts store (Idee Creativmarkt) for 12.95 the bottle - the same amount of Vallejo Gloss Varnish would cost 110+ Euros. It is very durable and dries very clearly, but has a definitely glossy sheen, stronger than Vallejo Gloss´. I can, however, brush on two or even three layers, and it doesn´t become too noticeably thick.
Then, I paint on a thin layer of Vallejo matt varnish to take off the sheen (unless I want to have it a metallic or ceramic look, in which case I leave it at two layers of Nerchau Rubens). Vallejo Barniz Mate, preferably the Model Color Variant, is the mattest varnish I´ve used so far.
Both brands work very well together, especially if you leave the first coats to dry for a little longer - the Rubens dries amazingly fast, though. I can usually brush on the next layer some 4-6 hours later. And it´s great to make lenses, headlight glasses and window effects.
Greatly recommended. Here´s a link to the manufacturer´s catalogue:

P.S.: It´s also very well suited to making water areas at less cost than resin, but greater amount of time.
