hi Kana,
Which camera are you planning to use?
I took this with an ED80 and a baader mpcc, no flattener/reducer, OAG, NEQ6.

you'll save yourself a lot of trouble if you focus equally on the guiding camera and method, I personally prefer the OAG, lot simpler than a separate guidescope, only caveat is that you need a sensitive guidecam. a significant part of your budget would go toward the two.
Options are the QHY5L2-mono or the Lodestar, latter being twice the cost of the L2.
HEQ5Pro is a brilliant mount. compact, very effective and does the job well. perfect for the ED80 or ED100.
I think the ED100 with a 0.8x reducer/flattener designed for it would be ideal. you get a bit more aperture with the 100.
focuser is also key, but not as important as the guiding and mount.
I use this OAG and works great. comes with a variety of options for the camera side and telescope side.

this reducer / flattener is designed for the ED80/100

remember to check the spacing requirements for your flattener.
you'll also need a decent dew heater, straps, the USB2EQ5 cable, a wireless game controller and you're all set. oh a baht mask as well.
Cheers
