Any Alternative Way To Retreive Data

Hi: Guys
Given the table below I want a select query that returns the AccountRepID with the largest single sale for each RegionID. In the event of a tie choose any single top AccountRepID to return.

CREATE TABLE [Sales] (
[SalesID] [int] IDENTITY (1, 1) NOT NULL ,
RegionID] [int],
[AccountRepID] [int],
[SalesAmount] [money]
)

If the data were
salesid,regionid,accountrepid,salesamount
1,101,31,$50
2,101,32,$25
3,102,31,$25
4,102,32,$25
5,102,31,$15

The query should return
regionid,accountrepid
101,31
102,31 or 102,32


Is there another way to get the data other than the following query:

select regionID,accountrepid FROM Sales
where salesamount in
(select max(salesamount) FROM Sales group by regionid)

Thanks
