I use a HAB-FPA1090SAW bought from Uputronics. Works pretty good for me. Wasn't cheap, $44 bucks shipped to me a couple of years ago. I use it with my Airspy, and it has just enough amplication to get the job done.
I'm sure there are other equally good amp/filter combos out there. I can't say this is better or worse than any other since I've never used any other one.
