the QHY5L2 and ASI120 are worth a look as well. They both have lots of small pixels and are very sensitive, so work well with shorter fl guide scopes. Both are also top notch planetary cams should you decide to go that way and both can image bright DSOs at a full 12 bits.
even the venerable QHY5 will do the guiding job well unless you want to guide at high speed.
