I was just looking at the Vixen Porta II and it is no longer available packaged with a tripod. I found just the mount head remaining on a couple of sites, but could not find a suitable tripod.
Regarding collimation of an 8" or smaller SCT, this takes just a few minutes and is rarely ever needed unless the OTA is bounced around hard, so I would not use that as a deciding factor. If it's good when new and never travels or ships again, it is likely that collimation may never need adjustment.
I find my SkyWatcher GoTo mounts very simple. I bought my first one earlier this year, I practiced for 30 minutes inside so I knew where all the menu commands were, then was off viewing and finding DSOs. The GoTo definitely makes my finding of faint DSOs faster and easier. I also like the <<Show me objects visible now>> command and think that's especially valuable for beginners. I can use the mounts manually too, of course, but the GoTo capability sure is convenient.
I would suggest a Vixen, Svbony or AstroTech refractor on a Vixen Porta II mount, with a Vixen tripod. You can purchase the Vixen items from another country - not a big deal these days.
