I am looking for recommendations for powered or un-powered fitler wheels suitable for my current 36mm unmounted filters. The QHY Compact wheel looks promising:

As does the Starlight Express wheel:

Any other or lower cost ideas folks?
Thanks

I am currently using the QHYCFW2-US-M (36mm unmounted) and it has worked flawlessly for me. When I upgraded from the QHY9 to 22 I either needed to change cables or run it via USB. Theo sent me a document to allow it to work via USB, took 5 minutes and have not had many problems.

I have found that if I get impatient and don't let it stop moving before sending a new command it just continues spinning (serial command messing up). My own fault for being impatient. Just a matter of disconnecting the USB to let it reset, or just waiting for it to stop before issuing another move :P

I have the SX wheel. It works fine, is quite light weight and has option of OAG seamlessly integrated plus you can get a bunch of different adaptors. My only (minor gripe) would be you have to fire up the computer and Maxim DL before plugging it in else it's "not detected".
Apart from that- no issues.
It holds 7 x 36mm unmounted filters without any dramas.
I have Baaders.
