To clean up the outputs of a DDS I am looking for a bandpass filter with

I'd definately go with Joerg on the LC's. The 1M6Hz filter (especially) with
it's Q of 16 would be useless in that single opamp bandpass form.
If you went L+C with a 10kohm source and load resistance then each filter
circuit has a sufficiently low capacitor value that a 50pF trimmer cap'
could provide the final tune. For inductors, I'd just use standard E12 Toko
items. -Then- use a times 2 opamp to return to unity gain.
