I personally went with the TSOAG9 from Teleskop Express, I think they still have a few second hand stock left. I got it second hand from their site for $190AUD, which is a little steep compared to the others but it's only 9mm long which allows for much more flexibility later on down the track with correctors and flatenners (Like using a CCD & Filterwheel or a DSLR with the common backfocus of 55mm). Plus it has a whole host of adapters available for it so you can really customise it if needed. I decided I'd rather spend the extra and future proof
In terms of guidecam its completely dependent on what you're imaging with. If it's a f/5 then the new QHY5-II or the QHY5L-II would be just fine as it's plenty sensitive. I have a QHY5-II on loan for review, yet to a clear night but already obvious its alot cleaner than my older QHY5 which I sold. Stay away from the Orion SSAG, its more expensive and some features are disabled. Teleskop also sell the 'ALccd' brand, which are clones of QHY but cheaper.
FYI I'll be buying from Teleskop-Express soon (
