I have a WO FLT 132. Very nice scope and a good way in to AP. Get a feather touch focuser and micro-touch it.
As for mount, there are lots available, depends on whether you are happy to fiddle. I have a G11 G2 and its a great mount and you can get them cheap as chips atm... but that will change, Can be very precise but needs a fair whack of fiddling. Heavy, excellent carrying capacity, highly customisable. The step up to G2 from G1 is a work in progress and a lot of people are impatient, (read: snarky), but... that's life.
I have also recently bought a PME 2 and, surprise, surprise, huge learning curve, fiddling etc etc. The more complex the gear, the more you fiddle.
Good luck
