I just bought myself a QHY16200a second hand loaded with Optolong 2" filters. The filters are 7nm Ha, 6.5nm S2 and O3 which isn't top of the line, but fit within my budget. I haven't had a chance to give it a go yet - waiting for an adapter to arrive (hopefully tomorrow) and some clear sky - but I'm happy to post some subs when I do get the chance to give you an idea of results.
Edit - I'm also closely following your other thread about a new scope, I'm highly doubting my ED102 will be able to illuminate an APS-H sensor, but we'll see.
Edit 2 - it's worth checking out Astromart, some sets on there going at reasonable price.
