If I use something like
[ntext2] <> \'1,032.5\',
I get this error:

If you would prefer not to cast, you can get by in some scenarios using LIKE or PATINDEX, as demonstrated on this MSDN thread: http://social.msdn.microsoft.com/Forums/en-US/transactsql/thread/6bd4c661-ea0b-435f-af78-097e61549d41
The LIKE expression, without wildcards, would be (in this case) roughly equivalent to a test for equality.
In this case, the expression would be:
[ntext2] NOT LIKE '1,032.5'
