SQL UNION-like query

I've got a table of items with prices. Nothing special really:

CREATE TABLE Variants (
[Name] nvarchar(50),
[MonthlyPrice] money
)

I need to get a query which gets all the entries that meet all the WHERE clauses, but such that all the items with a MonthlyPrice of 0 are placed <i>below </i>the items with a price.

So something like:

SELECT * FROM Variants WHERE (existingClauses) AND MonthlyPrice > 0 ORDER BY [Name] ASC
UNION
SELECT * FROM Variants WHERE (existingClauses) AND MonthlyPrice = 0 ORDER BY [Name] ASC

Is it possible to do it without a UNION? Because the table definition and existing clauses are already pretty complicated, and I don't want to have to duplicate the tables.
