Regards the speed I don't see many that are rated at 6k rpm in the lower price ranges, 3K rpm is a typical rating with incremental encoders. Yes, they can be run up to 5-6K rpm but they are not rated to run at that speed constant.!
There are currently tons of offers on Ebay for SGM7J-04AF + SGD7S-2R8A00 at $450 new. I bought one like this a while back for a little less. I just asked for cables and they included them with no extra charges.
You can even buy the model with absolute encoder separately for less (SGM7J-04A7 $160 + SGD7S-2R8A00 $260)

I didn't say 6000rpm is the nominal rating, but it's still useful for short rapid moves.
