Bandpass Filter Design 6Mhz/6.5Mhz Center Approx +/- 250khz passband for ATV system
I think that a solution using more "generically available" components such as an LC filter would be larger, more complex and far more troublesome to adjust. Ceramic filters are difficult to compete with, though mainstream suppliers don't pay them much attention. (Looking at Farnell, I see almost nothing below 800MHz nowadays!)

So I see two possible solutions : 

Stick with specialist suppliers (Toko and Murata come to mind, possibly Kyocera) and specialist distributors (used to be CirKit in the UK, but I haven't looked for them in years) or:

Transform the problem into one you can solve with available parts : e.g. use an oscillator and mixer as a frequency converter to a band for which you can easily find components; e.g. 10.7MHz. Or something more radical like ADC conversion and digital bandpass filters.

The first is definitely simpler...
