If you are going to get a monochrome camera, you could be waiting a long time for the rest of the stuff you need, eg Optolong filters are almost impossible to get now. Autofocusers and filter wheels also add to the angst of this supply chain timing.
Also, what are you going to use the 290 MM mini on? I have it on a ZWO 30F4 guide scope and it is barely usable because of the back focus. You need extenders to focus it properly with the 30F4. Guess what, those extenders are as rare as hens teeth.
PS Have you seen the deal on Ebay.com.au re your WO selection?
